MPM54322 3-16V, 3A, 500kHz Step-Down Converter

MPM54322 3-16V, 3A, 500kHz Step-Down Converter

Key Specifications

Features

• Wide 3V to 16V Input Voltage (VINx, where x = 1 or 2) Range
• Dual 3A and up to 6A for Parallel Operation
• MODE Pin to Select Output Voltage (VOUTx, where x = 1 or 2), Parallel Mode, and Timing via Pin-Strapping
• Remote Sense for Both Output Channels
• Configurable 500mA-Rated Low-Dropout (LDO) Regulator with VIN up to 3.6V
• Configurable Soft Start, Soft Shutdown, and Delay with MPS-Patented FLEX-Timer Sequence Control
• Configurable Reference Voltage (VREF) and Slew Rate
• Configurable Switching Frequency (fSW): 500kHz, 750kHz, 1MHz, and 1.25MHz
• Accurate VOUT, Output Current (IOUT), and Junction Temperature (TJ) Telemetry
• Open-Drain Power Good (PG) Indication and General Status Interrupt

Applications

• Storage and Networking
• FPGA and ASIC Power Supplies

Design Notes

• The step-down topology needs an inductor and output capacitor sized for the ripple at the switching frequency, not just the DC load.
• Keep the input loop short — high di/dt at the switch node sets conducted EMI.
