Data Sheet MxL7204 Dual 4A Power Module General Description Features The MxL7204 power module is a complete dual 4A or Dual 4A output (5A peak) single 8A output switch mode DC/DC power supply with Input Voltage Range: 4.5V to 20V an input voltage of 4.5V to 20V. It offers higher efficiency Output Voltage Range: 0.6V to 5.0V and improved thermal performance than the competition Current mode control / fast transient response while matching pinout and functionality. Power modules integrate the switching controller, power FETs, inductors Adjustable switching frequency and all supporting components. The MxL7204 supports Frequency synchronization (250kHz to 780kHz) two outputs each with an output voltage range of 0.6V to Overcurrent protection 5.0V, set by a single external resistor. Its high efficiency Output overvoltage protection design delivers up to 4A continuous current (5A peak) for each output. Only a few input and output capacitors are Thermally enhanced (15mm x 15mm x 2.82mm) LGA needed. package The device supports frequency synchronization, Applications multiphase operation, and output voltage tracking for supply rail sequencing. High Switching frequency and Telecom and Networking Equipment a current mode architecture enable a very fast transient response to line and load changes without sacrificing Industrial Equipment stability. Ordering Information - Back Page Fault protection features include overvoltage, overcurrent and over temperature protection. The power module is offered in a space saving and thermally enhanced 15mm 15mm 2.82mm LGA package. 95 90 85 MODE/PLLIN INTVCC 80 5.5V TO FREQ/PLLFLTR VIN 20V 13.3k 19.1k 10F VFB2 75 VFB1 x2 COMP1 COMP2 22pF 5Vout 780kHz 22pF V 70 OUT2 3.3Vout 780kHz V OUT1 VOUT1 VOUT2 3.3V/4A 2.5V/4A 2.5Vout 780kHz 100F TK/SS1 TK/SS2 100F MxL7204 65 1.8Vout 780kHz 0.1F RUN1 RUN2 0.1F 1.5Vout 500kHz PGOOD EXTVCC 60 1.2Vout 500kHz 1.0Vout 500kHz SGND PGND 55 0 0.5 1 1.5 2 2.5 3 3.5 4 I (A) OUT Figure 1: Typical Application Circuit Figure 2: Efficiency 12V IN www.maxlinear.com Rev 1B REV1A i/i Efficiency (%)Revision History MxL7204 Data Sheet Revision History Revision Release Date Change Description 1A 2/20/18 Initial Release 1B 8/8/18 Added paralleled output voltage programming equations and Table 7.
