Product Introduction

Overview

The LT8316EFE#PBF is a micropower, high-voltage flyback controller produced by Analog Devices Inc. This device is designed to operate without the need for an opto-isolator for regulation, making it a compact and efficient solution for isolated power supplies. It samples the output voltage from the isolated flyback waveform appearing across a third winding on the transformer, enabling quasi-resonant boundary mode operation. This mode improves load regulation, reduces transformer size, and maintains high efficiency.
