MPM54532 2.9-16V, 6A, 500kHz Step-Down Converter

MPM54532 2.9-16V, 6A, 500kHz Step-Down Converter

Key Specifications

Features

• 2.9V to 16V Input Voltage (VIN) Range
• 0.3V to 1.8V Output Voltage (VOUT) Range
• Dual 6A and Up to 12A for Parallel Mode
• MODE Pin to Select VOUT, Parallel Mode, and Timing via Pin-Strapping
• Remote Sense for Both Output Channels
• Configurable, Typically 500mA-Rated Low- Dropout (LDO) Regulator with Input Voltage Up to 3.6V
• Configurable Soft Start, Soft Shutdown, and Delay with 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

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.
