Overview

The MCP16301T-E/CH is a high-efficiency, fixed-frequency, step-down DC-DC converter capable of delivering up to 600mA of output current. It operates across a wide input voltage range of 4V to 30V and provides an adjustable output voltage from 2V to 15V using an integrated peak current mode control scheme. The device is housed in a compact 6-pin SOT-23 package, making it suitable for space-constrained point-of-load regulations.

Why Choose This Part

This regulator features internal compensation and soft-start, which reduces the external component count to just two capacitors, a power inductor, and two resistors for voltage setting. It is stable with low-cost ceramic capacitors and offers high efficiency across a broad load range, complemented by a low 7 microamp shutdown current to preserve power in standby modes.

Applications

Industrial 24V DC-DC Conversion
Stepping down standard 24V industrial rails to 3.3V or 5V for logic and sensor interfaces.
Microcontroller Bias Supply
Providing stable power for PIC and dsPIC microcontrollers in automotive and industrial control systems.
Set-Top Boxes and Modems
Efficient power regulation for consumer electronics requiring high-input voltage tolerance and small footprints.
Wall Cube Regulation
Secondary stage regulation for external power adapters to provide clean DC rails for internal circuitry.

Getting Started

To begin design, refer to the MCP16301 High-Voltage Buck Converter Evaluation Board (ADM00352) for layout and thermal performance benchmarks. Ensure that the input capacitor is placed as close as possible to the VIN and GND pins to minimize switching noise in the SOT-23-6 package.
