Overview

The MP2307DN-LF-Z is a compact 3 A synchronous step-down (buck) regulator IC from Monolithic Power Systems. It accepts input voltages from 4.75 V to 23 V and supports an adjustable output range from 0.925 V up to 20 V, providing a single positive output. The device is commonly used on small regulator modules and space-constrained PCBs where efficiency and low external component count are important.

Why Choose This Part

Synchronous topology gives higher efficiency than comparable non-synchronous regulators at moderate loads, reducing heat and easing thermal design. The 4.75 V to 23 V input range and adjustable output (down to 0.925 V) make it flexible for a wide variety of system rails. Its integrated switching FETs and small-solution footprint reduce external component count and PCB area, which helps in compact or module-based designs.

Applications

Point-of-load regulation
Provide low-voltage rails for microcontrollers, FPGAs, or ASICs from 12 V or battery bus supplies.
Board-level regulator modules
Used on small DC-DC module boards and compact power supplies where board area is limited.
Battery-powered systems
Step down multi-cell Li-ion or other battery packs (within the input range) to regulated system rails.
Industrial and communications equipment
Local regulation for sensors, transceivers, and control electronics in 12 V and 24 V systems.
Embedded and handheld devices
Powering peripherals and subsystems in portable or space-constrained consumer products.

Getting Started

Begin with the Monolithic Power Systems datasheet and reference schematic to pick recommended inductor, input/output capacitors, and compensation components. Pay close attention to PCB layout guidance for switching regulators: keep switching loops short, place input capacitors close to VIN and GND, and use adequate copper and thermal vias for heat dissipation. For early prototyping, use a breakout or ready-made regulator module based on the MP2307 to validate voltages and thermal behavior before final PCB layout.
