Then if multiple adjustments are required, multiply all of the normalized values together, then multiply that product by the value indicated on the power loss curve in Fig. 2. The resulting product is the final power loss based on all factors. See example no. 1.To make adjustments to the SOA curve in Fig. 3, determine your maximum PCB Temp & Case Temp at the maximum operating current of each iP1203PbF . Then, add the correction temperature from the normalized curves in Figs. 4, 5, 6 or 7 to the T X axis intercept (see procedure no. 2 above) in Fig. 3. When multiple adjustments are required, add all of the temperatures together, then add the sum to the T X axis intercept in Fig. 3. See example no. 2.Operating Conditions for the following examples:Output Current = 12A Input Voltage = 13.2V Inductor = 0.6µHOutput Voltage = 1.2VSw Freq= 400kHzExample 1) Adjusting for Maximum Power Loss:(Fig. 2)Maximum power loss = 4.1W(Fig. 4)Normalized power loss for input voltage ≈ 1.025(Fig. 5)Normalized power loss for output voltage ≈ 0.97(Fig. 6)Normalized power loss for frequency ≈ 1.08(Fig. 7)Normalized power loss for inductor value ≈ 1.08Adjusted Power Loss = 4.1 x 1.025 x 0.97 x 1.08 x 1.08 ≈ 4.75WApplying the Safe Operating Area (SOA) CurveThe SOA graph incorporates power loss and thermal resistance information in a way that allows one to solve for maximum current capability in a simplified graphical manner. It incorporates the ability to solve thermal problems where heat is drawn out through the printed circuit board and the top of the case.Procedure1)Draw a line from Case Temp axis at T CASE to the PCBTemp axis at T PCB .2)Draw a vertical line from the T X axis intercept to the SOAcurve.

The desired fre-quency is set by placing an external resistor to the R T pin of the iP1203PbF . See Fig. 9 for the proper resistor value.The iP1203PbF is capable of accepting an external digital synchronization signal. Synchronization will be enabled by the rising edge clock. The free run-ning oscillator frequency is twice the switching fre-quency. During synchronization, R T is selected such that the free running frequency is 20% below the synchronization frequency. The maximum synchro-nization frequency that iP1203PbF can accept is 800kHz. Note that the actual switching frequency is half the synchronization frequency.iP1203PbF User s Design GuidelinesThe iP1203PbF is a single output 15A power block consisting of optimized power semiconductors, PWM control and its associated passive components. It is based on a synchronous buck topology and offers an optimized solution where space, efficiency and noise caused by parasitics are of concern. The power block operates with fixed frequency voltage mode control. The iP1203PbF components are integrated in a land grid array (LGA) package.V IN / Enabling the OutputThe input operating voltage range of the iP1203PbF is 5.5V to 13.2V.The iP1203PbF output is turned on upon application of input voltage. The V IN slew rate should not exceed 50mV/µs. The converter can also be turned on and off by releasing or pulling the SS pin low through a logic level MOSFET, the drain of which connects to the soft start pin (see Fig.12). This feature can be useful if sequencing or different start-up timing of dif-ferent system outputs are required. In situations where the output has undergone a latched shutdown due to overvoltage, cycling Vin will reset the output. Cycling soft start pin will not unlatch the output.Soft StartThe Soft Start function provides a controlled rise of the output voltage, thus limiting the inrush current.The soft start function has an internal 25µA +/-20%current source that charges the external soft start capacitor C ss up to 3V. During power-up, the output voltage starts ramping up only after the charging volt-age across the C ss capacitor has reached a 0.8Vtyp threshold, as shown in Fig. 13.Fig. 13: Power Up Threshold3V0.8VtypV Css V OUTFig.12: Soft Start/Enable CircuitFrequency and SynchronizationOvercurrent Protection HICCUPThe overcurrent protection function of the iP1203PbF offers a hiccup feature. During overloads, when the overcurrent trip threshold is reached, the power sup-ply output shuts down and attempts to restart (out-put HICCUP mode). The time duration between the shutdown of the output and the restart is determined by the time it takes to discharge the soft start ca-pacitor. Typically, the discharge time of the soft start capacitor is 10 times the charge time. The duty cycle of the hiccup process is typically 5%. The output will stay in hiccup indefinitely until the overload is re-moved. The typical overcurrent trip threshold of the device is internally set at 30A. The overcurrent shut-down / HICCUP threshold is about ±30% accurate.The iP1203PbF overcurrent shutdown and HICCUP threshold can be set externally by adding R OCSET re-sistor from OCSET pin. Refer to Fig.8 for R OCSET se-lection.Overvoltage Protection (OVP)Overvoltage is sensed through output voltage sense pin FB s . The OVP threshold is set to 115% of the output voltage. Upon overvoltage condition, the OVP forces a latched shutdown. In this mode, the upper FET turns off and the lower FET turns on, thus crowbaring the output. Reset is performed by recy-cling the input voltage. Overvoltage can be sensed by either connecting FB s to its corresponding output through a separate output voltage divider resistor network, or it can be connected directly to its corre-sponding feedback pin FB. For Type III control loop compensation, FB s should be connected through voltage dividers only.Refer to the iP1203PbF Design Procedure section on how to set the OVP trip threshold.PGOODThis is an output voltage status signal that is open collector and is pulled low when the output voltage falls below 85% of the output voltage. High state in-dicates that outputs are in regulation. The PGOOD pin can be left floating if not used.Thermal ShutdownThe iP1203PbF provides thermal shutdown. The threshold typically is set to 140°C. When the trip threshold is exceeded, thermal shutdown turns the output off. Thermal shutdown is not latched and au-tomatic restart is initiated when the sensed tempera-ture drops to the normal range.Only a few external components are required to com-plete a dual output synchronous buck power supply using iP1203PbF. The following procedure will guide the designer through the design and selection pro-cess of these external components.A typical application for the iP1203 is:V IN = 12V, V OUT = 1.5V, I OUT = 15A, f sw = 300kHz, V p-p == 50mVSetting the Output VoltageThe output voltage of the iP1203PbF is set by the 0.8V reference Vand external voltage dividers.Fig. 14: Typical Scheme for Output Voltage Setting V OUT is set according to equation (1):V OUT = V REF x (1 + R 2 /R 5 ) (see Fig. 14)(1)Setting R 2 to 1K, V OUT to 1.5V and V REF to 0.8V, will result in R 5= 1.14 Kohms. Final values can be se-lected according to the desired accuracy of the out-put.To set the output voltage for Type III compensation,refer to equation (24) in Type III compensation sec-tion.iP1203PbF Design ProcedureSetting the Overvoltage TripThe output of the iP1203 will shut down if it experi-ences a voltage in the range of 115% of V OUT . The overvoltage sense pin FB s is connected to the out-put through voltage dividers, R26 and R27 (Fig. 14),and the trip setpoint is programmed according to equation (1). A separate overvoltage sense pin FB s is provided to protect the power supply output if for some reason the main feedback loop is lost (for in-stance, loss of feedback resistors). An optional 100pF capacitor (C14) is used for delay and filtering.If this redundancy is not required and if a Type II con-trol loop compensation scheme is utilized, FB s pin can be connected to FB.Selecting the Soft-Start CapacitorThe soft start capacitor C ss is selected according to equation (2):t ss = 40 x C ss(2)where,t ss is the output voltage ramp time in milliseconds,and C ss is the soft start capacitor in µF.A 0.1µF capacitor will provide an output voltage ramp-up time of about 4ms.Input Capacitor SelectionThe switching currents impose RMS current require-ments on the input capacitors. Equation (3) allows the selection of the input capacitors.where, I out is the output current, and D is the duty cycle and is expressed as:D = V OUT / V IN .For the above example D= 0.13 and, using equation (3) the capacitor rms current yields 5.0A.For Type II compensation,(3))1(D D I I out RMS −=For better efficiency and low input ripple, select low ESR ceramic capacitors. The amount of the capaci-tors is determined based on the rms rating. In the above example, a total of 3 x 22µF, 2A capacitors will be required to support the input rms current.Output Capacitor C O SelectionSelection of the output capacitors depends on two factors:a. Low effective ESR for ripple and load transient re-quirementsTo support the load transients and to stay within a specified voltage dip ∆V due to the transients, ESR selection should satisfy equation (4):R ESR ≤ ∆V / I Loadmax(4)Where,I Loadmax is the maximum load current.If output voltage ripple is required to be maintained at specified levels then the expression in equation (5) should be used to select the output capacitors.R ESR ≤ V p-p / I ripple(5)Where,V p-p is the peak to peak output ripple voltage .I ripple is the inductor peak-to peak ripple current.In addition, the voltage ripple caused by the output capacitor needs to be significantly smaller than the ripple caused by the ESR of the capacitor. Use equa-tion (6) to satisfy this requirement.If the inductor current ripple I ripple is 30% of I OUT1, the 50mV peak to peak output voltage ripple requirement will be met if the total ESR of the output capacitors is less than 11m Ω. This will require 2 x 470µF POSCAP capacitors. Additional ceramic capacitors can be added in parallel to further reduce the ESR. Care should be given to properly compensate the control loop for low output capacitor ESR values.When selecting output capacitors, it is important to consider the overshoot performance of the power sup-ply. If the amount of capacitance is not adequate, then,when unloading the output, the magnitude of the over-shoot due to stored inductor energy, and depending on the speed of the response of the control loop, can exceed the overvoltage trip threshold of the iP1203PbF and can cause undesirable shutdown of the output. The magnitude of the overshoot should be kept below 1.125V OUT . To prevent the overshoot from tripping the output a delay can be added by in-stalling capacitor C14 as shown in Fig.14.b. StabilityThe value of the output capacitor ESR zero frequency f esr plays a major role in determining stability. f esr is calculated by the expression in equation (7).f ESR = 1 / (2 π x R ESR x C O )(7)Details on how to consider this parameter to design for stability are outlined in the control loop compen-sation section of this datasheet.Inductor L O SelectionInductor selection is based on trade-offs between size and efficiency. Low inductor values result in smaller sizes, but can cause large ripple currents and lower efficiency. Low inductor values also benefit the tran-sient performance.The inductor L o is selected according to equation (8):L O = V out x (1 - D) / (f sw x I ripple )(8)For the above example, and for I ripple of 30% of I OUT , L O is calculated to be 1.0µH.The core must be selected according to the peak of maximum output current.(6)ESRs o R f C ××>π210Control Loop CompensationThe iP1203PbF feedback control is based on single loop voltage mode control principle.The goal in the design of the compensator is to achieve the highest unity gain (0 db) crossover fre-quency with sufficient phase margin for the closed loop transfer function. The LC filter of the power sup-ply introduces a double pole with 40db/dec slope and 180° phase lag. The 180° phase contribution from the LC filter is the source of instabilty.The resonant frequency of the LC filter is expressed by equation (9):(9)The error amplifier of the iP1203PbF PWM controlleris transconductance amplifier, and its output is avail-able for external compensation.Two types of compensators are studied in this sec-tion. The first one is called Type II and it is used to compensate systems the ESR frequency f esr (equa-tion 7) of which is in the midfrequency range and Type III that can be used for any type of output capacitors and have a wide range of f esr .For output voltage settings less than 1.0V that use low ESR ceramic capacitors, it is recommended that the unity gain crossover frequency be set around 20kHz to maintain stable operation.where, g m is the transconductance of the error am-plifier.(12)Follow the steps below to determine the feedback loop compensation component values:1.

This is done by adding a capacitor C opt in Fig.15 from the output of the error amplifier (CC pin of iP1203PbF) to ground.This pole is given by equation (15):C opt is found from equation (16) by rearranging the terms in equation (15) and by setting f p2 = f sw / 2:(16)Fig. 16: Typical Type III Compensation and its Gain PlotType IIIThe Type III compensation scheme allows the use of any type of capacitors with ESR frequency of any range. This scheme suggests a double pole double zero compensation and requires more components around the error amplifier to achieve the desired gain and phase margins. Fig. 13 represents the Type III compensation network for iP1203PbF.The transfer function of the Type III compensator is given by equation (17)2.

Output Voltage Turns Off When Voltage at FB s Pin Exceeds 15% of FB (0.8V)For stable and noise free operation of the whole power system, it is recommended that the design-ers use the following guidelines:1. Follow the layout scheme presented in Fig. 23. Make sure that the output inductor L is placed as close to iP1203PbF as possible to prevent noise propagation that can be caused by switching of power at the switching node Vsw, to sensitive cir-cuits.2. Provide a mid-layer solid ground plane with con-nections to the top layer through vias. The PGND pads of iP1203PbF also need to be connected to the same ground plane through vias.3. To increase power supply noise immunity, place input and output capacitors close to one another, as shown in the layout diagram. This will provide short high current paths that are essential at the ground terminals.4. Although there is a certain degree of VIN bypass-ing inside the iP1203PbF, the external input decoupling capacitors should be as close to the device as pos-sible.5. The feedback track from the output VOUTto FB should be routed as far away from noise generating traces as possible.6. The compensation components and the Vref by-pass capacitor should be placed as close as pos-sible to their corresponding iP1203PbF pins, away from noise generating traces.7. Refer to IR application note AN-1029 (Optimizinga PCB Layout for an iPOWIR Technology Design) to determine what size vias and copper weight and thickness to use when designing the PCB.8.
