Product Details
AP62300WU-7 - 3A Synchronous Buck Converter 4.5V–18V Input (SOT23-6)
AP62300WU-7 is a high-efficiency synchronous step-down (buck) DC-DC converter from Diodes Incorporated, designed to deliver up to 3A output current with wide input voltage support and excellent power efficiency for compact power designs.
This page is written for product identification and engineering selection guidance. Always verify final limits using the manufacturer's latest datasheet revision for design sign-off.
Overview
AP62300WU-7 is a fully integrated synchronous buck converter optimized for high efficiency and compact PCB layout. It integrates both high-side and low-side MOSFETs, reducing external component count and simplifying power design.
With a wide input voltage range and high switching frequency, it is ideal for distributed power systems, point-of-load (POL) regulation, and embedded applications requiring stable and efficient DC voltage conversion.
Key Advantages
Synchronous design minimizes power loss and improves system efficiency.
Supports up to 3A load, suitable for processors and high-current loads.
Integrated MOSFETs reduce external components and PCB footprint.
Includes overcurrent, thermal shutdown, and undervoltage protections.
Feature Summary
Operates from 4.5V to 18V, suitable for various power rails.
Up to 3A continuous load capability.
Allows use of small inductors and capacitors for compact designs.
Includes OCP, OTP, and UVLO for reliable system operation.
Package & Footprint
The AP62300WU-7 is housed in a compact SOT23-6 package, ideal for space-constrained applications and high-density PCB layouts.
