Bypass them with a high quality ceramic capacitor to the GND pins.GND PINSThese pins return operational bias current to system ground. VO is measured with respect to GND. The GND pin sinks reference current established by the external resistor R T.VO PINSince this pin measures DCR voltage drop it is critical that it be Kelvin connected to the buck inductor output. Power accuracy may be degraded if the voltage at this pin is below VO min.VCS PINA switched current source internal to the IR3721 maintains the average voltage of this pin equal to the voltage of the VO pin. The average current into this pin is therefore proportional to buck inductor current. VRT PINA voltage reference internal to the IR3721 drives the V RT pin while the pin current is monitored and used to set the amplitude of the current monitor switched current source I REF. Connect this pin to GND through a precision resistor network R T. This network may include provision for canceling the positive temperature coefficient of the buck inductor’s DC resistance (DCR).VK PINThe voltage of the VK pin is used to modulate the amplitude of the DI pin. This is one of the terms used to determine the product of the multiplier output. If VK is connected to a fixed voltage then the output of the multiplier is proportional to current. If VK is connected to the buck converter output voltage then the output of the DI driven RC filter is proportional to power.DI PINThe Dl pin output has a duty ratio proportional to the current into VCS, and an amplitude equal to the voltage at the VK pin. The DI pin is intended to drive an external low pass filter. The output of this filter is the product of the current and voltage terms.FUNCTIONAL DESCRIPTIONPlease refer to the Functional Description Diagram below. Power flow from the buck converter inductor is the product of output voltage times the current I L flowing through the inductor.Power is measured with the aid of InternationalRectifier’s proprietary TruePower™ circuit. Current is converted to a duty ratio that appears at the DI pin. The duty ratio of the DI pin isΤ⋅)+(⋅=R T 2CS 1CS L RATIO DUTY V RR R DCR I DI Equation 1The full-scale current that can be measured corresponds to a duty ratio of one.The amplitude of the DI pin is the voltage appearing at pin VK. If a fixed voltage is applied to VK then the output of the RC filter driven by DI will be proportional to inductor current I L .If VO is applied to V K as shown in the figure then the output of the DI driven RC network will beproportional to power. The full-scale voltage that can be measured is established on the chip to be 1.8V.The full scale power P FS that can be measured is the product of full-scale voltage and full scale current.Figure 1 Functional Description DiagramTHERMAL COMPENSATION FOR INDUCTOR DCR CURRENT SENSINGThe positive temperature coefficient of the inductor DCR can be compensated if R T varies inversely proportional to the DCR. DCR of a copper coil, as a function of temperature, is approximated by)⋅)(+(⋅)(=)(Cu R R TCR T T T DCR T DCR -1Equation 2T R is some reference temperature, usually 25 °C, and TCR Cu is the resistive temperature coefficient ofcopper, usually assumed to be 0.39 %/°C near room temperature. Note that equation 2 is linearly increasing with temperature and has an offset of DCR(T R ) at the reference temperature.If R T incorporates a negative temperature coefficient thermistor then temperature effects of DCR can be minimized. Consider a circuit of two resistors and a thermistor as shown below.RpFigure 2 R T NetworkIf Rth is an NTC thermistor then the value of the network will decrease as temperature increases. Unfortunately, most thermistors exhibit far more variation with temperature than copper wire.

Kelvin degrees are used in the exponential term of equation 3. If R S is large and R P is small, thecurvature of the equivalent network resistance can be reduced from the curvature of the thermistor alone. Although the exponential equation 3 can nevercompensate linear equation 2 at all temperatures, a spreadsheet can be constructed to minimize error over the temperature interval of interest. Theequivalent resistance R T of the network shown as a function of temperature is)(++=)(T R R R T R th p s T 111Equation 4using R th (T) from equation 3.Equation 2 may be rewritten as a new function of temperature using equations 2 and 4 as follows:())(+⋅)(=)(ΤT DCR R R T R V T I 2CS 1CS T R FS Equation 5With Rs and Rp as additional free variables, use a spreadsheet to solve equation 5 for the desired full scale current while minimizing the I FS (T) variation over temperature.TYPICAL 2-PHASE DCR SENSING APPLICATIONThe IR3721 is capable of monitoring power in a multiphase converter. A Two Phase DCR Sensing Circuit is shown below. The voltage output of any phase is equal to that of any and every other phase because they are electrically connected and monitored at VO as before.Output current is the sum of the two inductor currents (I L1 + I L2). Superposition is used to derive the transfer function for multiphase sensing.

Because the voltage on the shunt resistor is directly proportional to the current I L through the inductor, R CS2 and C CS2 do not need to match the L / DCR time constant. Because the value of the shunt resistance does not change with temperature as the inductor DCR does, R T can be a fixed resistor.IFigure 4 Resistor Sensing CircuitCOMPONENT SELECTION GUIDELINES Use a 0.1 μF, 6.3V, X7R ceramic bypass capacitorfrom VDD to GND and from VK to GND.Filter the DI output with an RC filter to give a stable analog representation of the current or power. Some of the DI source resistance of this filter is internal to the IR3721 and specified in the electrical specifications table. Add twenty thousand to fifty thousand additional ohms externally to minimize resistance variation. As the DI source resistance increases beyond these guidelines, the voltage measurement error caused by non-ideal voltmeter conductance will increase.Select a filter capacitor that limits 512 kHz sampling frequency ripple to an acceptable value. Sampling frequency ripple will appear as an error, but can be reduced 20 dB for each decade that the filter corner frequency is below 512 kHz. Select a capacitor value that achieves the desired balance between low sampling frequency ripple and adequate bandwidth. Resistor current sensingFor resistor current sensing select a precision resistor for R T inside the R T resistance range limits specified in the Electrical Specifications table, such as 25.5kΩand 1% tolerance.Next, select a shunt resistor that will provide the most current sensing voltage while also considering the allowable power dissipation limitations. The DI output will saturate to the VK voltage when full scale current I FS flows through this shunt. Recommended maximum current sensing voltage range is 5 to 150 mV. Maximum sensing voltages less than 5 mV will cause comparator input offset voltage errors to dominate, and voltages larger than 150 mV will cause comparator leakage current, I CS, errors to dominate. Select R CS2 to be the next higher standard value resistor from (R SHUNT·I FS·R T) / V RT in order to accommodate full scale current I FS.Bypass VCS to VO with capacitor C CS2. The value of this capacitor limits the bandwidth, but is required because it is the integrator of the delta sigma modulator. Consider selecting the value of C CS2 to place a filter corner frequency at 5 kHz, which will reduce sampling ripple by 40 dB.DCR current sensingSelect an R T network resistance between 20kΩ and 45.3kΩ. Consider the R T network of Figure 5 for DCR current sensing.26.1 kΩ, 1%15.0 kΩ, 1%2.00 kΩ, 1%Murata ThermistorNCP15WB473F03RC47 kΩ, 1%Figure 5 R T networkThe resistance of the network above at 25°C, R T(25), is 37.58kΩ. Over temperature R T(T) is multiplied by copper resistance, DCR(25)·(1+(T-25)·0.0039), divided by (DCR(25)·( R T(25)) to normalize the results, and plotted as nominal error in Figure 6.Figure 6 Nominal error vs. TemperatureNote that the error due to temperature compensation at 25°C is zero, assuming ideal R T components. At other temperatures the results are over or under reported by the factor in percent indicated.Proceed to calculate R SUM, defined as the sum ofR CS1 plus R CS2, as follows.R SUM=I FS·DCR(25) ·R T(25) / V RTAgain, I FS is full scale current and V RT is the reference voltage establishing the current in R T.Estimate the capacitance C CS1 with the following equation.SUMCS R DCR LC ⋅)(⋅>2541Choose a standard capacitor value larger than indicated by the right hand side of the inequality above.Calculate the equivalent resistance R eq .R eq = L / (DCR(25) ·C CS1)We now have two equations, R SUM = R CS1 + R CS2 and Req = (R CS1 · R CS2) / (R CS1 + R CS2). Calculate R CS1 and R CS2 using the following two equations.⎟⎟⎟⎟⎟⎟⎠⎞⎜⎜⎜⎜⎜⎜⎝⎛⋅+⋅=2R R 411R R SUM eq SUM CS1- and⎟⎟⎟⎟⎟⎟⎠⎞⎜⎜⎜⎜⎜⎜⎝⎛⋅⋅=2R R 411R R SUM eq SUM 2CS --Use the next higher standard 1% value than indicated in the equations above. This will insure that full scale current can be measured.Bypass VCS to VO with capacitor C CS2. The value of this capacitor limits the bandwidth, but is required because it is the integrator of the delta sigmamodulator. Consider selecting the value of C CS2 to place a filter corner frequency at 5 kHz, which will reduce sampling ripple by 40 dB.分销商库存信息: IRIR3721MTRPBF。
