LM2704Micropower Step-up DC/DC Converter with 550mA Peak Current LimitGeneral DescriptionThe LM2704is a micropower step-up DC/DC in a small 5-lead SOT-23package.A current limited,fixed off-time control scheme conserves operating current resulting in high efficiency over a wide range of load conditions.The 21V switch allows for output voltages as high as 20V.The low 400ns off-time permits the use of tiny,low profile inductors and capacitors to minimize footprint and cost in space-conscious portable applications.The LM2704is ideal for LCD panels requiring low current and high efficiency as well as white LED applications for cellular phone back-lighting.The LM2704can drive up to 8white LEDs from a single Li-Ion battery.Featuresn 550mA,0.7Ω,internal switchn Uses small surface mount

intended to be functional,but device parameter specifications may not be guaranteed.For guaranteed specifications and test conditions,see the Electrical Characteristics.Note2:The maximum allowable power dissipation is a function of the maximum junction temperature,T J(MAX),the junction-to-ambient thermal resistance,θJA, and the ambient temperature,T A.See the Electrical Characteristics table for the thermal resistance.The maximum allowable power dissipation at any ambient temperature is calculated using:P D(MAX)=(T J(MAX)−T A)/θJA.Exceeding the maximum allowable power dissipation will cause excessive die temperature.Note3:The human body model is a100pF capacitor discharged through a1.5kΩresistor into each pin.The machine model is a200pF capacitor discharged directly into each

WaveformLM27047Operation(Continued)The LM2704features a constant off-time control scheme.Operation can be best understood by referring to Figure 2and Figure 3.Transistors Q1and Q2and resistors R3and R4of Figure 2form a bandgap reference used to control the output voltage.When the voltage at the FB pin is less than 1.237V,the Enable Comp in Figure 2enables the device and the NMOS switch is turned on pulling the SW pin to ground.When the NMOS switch is on,current begins to flow through inductor L while the load current is supplied by the output capacitor C OUT .Once the current in the inductor reaches the peak current limit,the CL Comp trips and the 400ns One Shot turns off the NMOS switch.The SW voltage will then rise to the output voltage plus a diode drop and the inductor current will begin to decrease as shown in Figure 3.During this time the energy stored in the inductor is transferred to C OUT and the load.After the 400ns off-time the NMOS switch is turned on and energy is stored in the inductor again.This energy transfer from the inductor to the output causes a stepping effect in the output ripple as shown in Figure 3.This cycle is continued until the voltage at FB reaches 1.237V.When FB reaches this voltage,the enable compara-tor then disables the device turning off the NMOS switch and reducing the Iq of the device to 40uA.The load current is then supplied solely by C OUT indicated by the gradually decreasing slope at the output as shown in Figure 3.When the FB pin drops slightly below 1.237V,the enable compara-tor enables the device and begins the cycle described pre-viously.The SHDN pin can be used to turn off the LM2704and reduce the I q to 0.01µA.In shutdown mode the output voltage will be a diode drop lower than the input voltage.Application InformationINDUCTOR SELECTIONThe appropriate inductor for a given application is calculated using the following equation:where V D is the schottky diode voltage,I CL is the switch current limit found in the Typical Performance Characteris-tics section,and T OFF is the switch off time.When using this equation be sure to use the minimum input voltage for the application,such as for battery powered applications.For the LM2704constant-off time control scheme,the NMOS power switch is turned off when the current limit is reached.There is approximately a 200ns delay from the time the current limit is reached in the NMOS power switch and when the internal logic actually turns off the switch.During this 200ns delay,the peak inductor current will increase.This increase in inductor current demands a larger saturation current rating for the inductor.This saturation current can be approximated by the following equation:Choosing inductors with low ESR decrease power losses and increase efficiency.Care should be taken when choosing an inductor.For appli-cations that require an input voltage that approaches the output voltage,such as when converting a Li-Ion battery voltage to 5V,the 400ns off time may not be enough time to discharge the energy in the inductor and transfer the energy to the output capacitor and load.This can cause a ramping effect in the inductor current waveform and an increased ripple on the output ing a smaller inductor will cause the I PK to increase and will increase the output voltage ripple further.This can be solved by adding a 4.7pF capaci-tor across the R F1feedback resistor (Figure 2)and slightly increasing the output capacitor.A smaller inductor can then be used to ensure proper discharge in the 400ns off time.DIODE SELECTIONTo maintain high efficiency,the average current rating of the schottky diode should be larger than the peak inductor cur-rent,I PK .Schottky diodes with a low forward drop and fast switching speeds are ideal for increasing efficiency in por-table applications.Choose a reverse breakdown of the schottky diode larger than the output voltage.CAPACITOR SELECTIONChoose low ESR capacitors for the output to minimize output voltage ripple.Multilayer ceramic capacitors are the best choice.For most applications,a 1µF ceramic capacitor is sufficient.For some applications a reduction in output volt-age ripple can be achieved by increasing the output capaci-tor.Local bypassing for the input is needed on the LM2704.Multilayer ceramic capacitors are a good choice for this as well.A 4.7µF capacitor is sufficient for most applications.For additional bypassing,a 100nF ceramic capacitor can be used to shunt high frequency ripple on the input.LAYOUT CONSIDERATIONSThe input bypass capacitor C IN ,as shown in Figure 1,must be placed close to the IC.This will reduce copper trace resistance which effects input voltage ripple of the IC.For additional input voltage filtering,a 100nF bypass capacitor can be placed in parallel with C IN to shunt any high fre-quency noise to ground.The output capacitor,C OUT ,should also be placed close to the IC.Any copper trace connections for the Cout capacitor can increase the series resistance,which directly effects output voltage ripple.The feedback network,resistors R1and R2,should be kept close to the FB pin to minimize copper trace connections that can inject noise into the system.The ground connection for the feed-back resistor network should connect directly to an analog ground plane.The analog ground plane should tie directly to the GND pin.If no analog ground plane is available,the ground connection for the feedback network should tie di-rectly to the GND pin.Trace connections made to the induc-tor and schottky diode should be minimized to reduce power dissipation and increase overall efficiency.L M 2704 8Application Information(Continued)20031509FIGURE 4.White LED Application20031534FIGURE 5.Li-Ion 5V
