AP64500 - DIODES

AP64500 5A LOW IQ SYNCHRONOUS BUCK

Pin Assignments The AP64500 is a 5A, synchronous buck converter with a wide input voltage range of 3.8V to 40V. The device fully integrates a 45mΩ highside power MOSFET and a 20mΩ low-side power MOSFET to provide high-efficiency step-down DC-DC conversion. The AP64500 device is easily used by minimizing the external component count due to its adoption of p.

Features

Frequency Spread Spectrum (FSS) with a switching frequency jitter of ±6%, which reduces EMI by not allowing emitted energy to stay in any one frequency for a significant period of time. The device is available in an SO-8EP package. BST 1 VIN 2 EN 3 RT/CLK 4 TOP VIEW EXPOSED PAD 9 SO-8EP 8 SW 7 GND 6 COMP 5 FB Features
