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.

Features
- Single output with the built-in power MOSFET.
- High efficiency 85% at 24V input and 5 V/1.2 A output with 200kHz operation.
- Stable operation with current mode control.
- Switching frequency selectable from 30 kHz to 400 kHz.
- ON/OFF function: Current consumption 0.1mA(max.) at OFF mode.
- Current consumption of the VCC terminal during operation is 0.5mA(typ.).
- Protection functions: Over current limitation for the power MOSFET Soft start (8 ms) Short-circuit protection with the timer and latch (90ms delay time) Thermal shut down Protection for opened rectifier diode
- SOP-8pin package with the exposed pad.
