DIOAP63200WU-7
Overview
The AP63200WU-7 is a 2A synchronous buck converter with a wide input voltage range of 3.8V to 32V, making it suitable for distributed power bus systems. It features a proprietary gate driver design to reduce electromagnetic interference (EMI) and utilizes Frequency Spread Spectrum (FSS) to further minimize EMI noise. The device integrates high-side and low-side MOSFETs to provide a high-efficiency step-down solution in a compact TSOT26 package.
Why Choose This Part
This regulator features an ultra-low shutdown current of 1uA and a quiescent current of 22uA, which is ideal for power-sensitive designs. Its 500kHz switching frequency with Pulse Frequency Modulation (PFM) maintains high efficiency even at light loads. Integrated safety features include cycle-by-cycle peak current limiting, overvoltage protection, and thermal shutdown.
Applications
Key Specifications
Getting Started
Designers should follow the recommended PCB layout in the datasheet to manage heat dissipation through the TSOT26 package and minimize EMI. Ensure that a low-ESR ceramic capacitor is placed close to the VIN and GND pins to stabilize the input supply. Evaluation of the adjustable output voltage is performed by selecting the appropriate feedback resistor divider for the 1.2V reference.
