HL9701

Secondary-Side Synchronous Rectifier Controller for Flyback Converters

Return

Overview

The HL9701 is a secondary-side synchronous rectifier (SR) controller for isolated flyback converters. By implementing proprietary turn-off control algorithm, the HL9701 can reliably support discontinuous conduction mode (DCM), quasi-resonant (QR), and continuous conduction mode (CCM) operation, which helps to design robust flyback converters.

Features

Compatibility of continuous conduction mode (CCM), quasi-resonant (QR), and discontinuous conduction mode (DCM)
Compatible with high side and low side application
Wide input voltage ranges up to 26.5V
Optimized SR gate turn-off threshold control
Proprietary CCM SR turn-off control algorithm
Minimized SR turn-on/off propagation delay
SR MOSFET gate passive clamp
Low power saving mode
Small footprint with SOT-23 6 pin package
