FA7764中文资料富士通数据手册PDF规格书

Overview

The FA7764N is a single output step-down DC-DC converter with built-in power MOSFET.

Featuring a high voltage process, it is suitable for the DC-DC converter with input voltages of up to 45 V and output currents of up to 1.5 A.

It operates with the current mode control and also it can reduce external parts. Furthermore it achieves a fast response.

The circuit protections are built-in to achieve safety power supply circuit.
