Introduction

AI Translation

HT6908 is a low forward-voltage-drop diode emulator IC that, when combined with an external switch, replaces a Schottky diode in high-efficiency flyback converters. The device regulates the forward voltage drop of an external synchronous rectification MOSFET to approximately 40mV and turns off when the voltage goes negative. For battery charging applications where the output voltage may be low, the output is in a short-circuit condition, or a high-side synchronous rectification configuration is used, the HT6908 can generate its own supply voltage. Its programmable ringing detection circuit prevents false turn-on of the device due to Vds oscillation during discontinuous conduction mode and quasi-resonant operation.

Features

AI Translation
  • Wide output range down to 0V, no short-circuit current through body diode
  • No auxiliary winding required for high-side or low-side rectification
  • Ringing detection prevents false turn-on during DCM and quasi-resonant operation
  • Compatible with standard and logic-level synchronous rectification MOSFETs
  • Energy Star compliant
  • ~30ns fast turn-off and turn-on delay
  • ~100µA quiescent current
  • Supports DCM, CCM, and quasi-resonant operation
  • Supports both high-side and low-side rectification

Applications

AI Translation
  • USB PD fast charger
  • Adapter
  • Flyback power supply with extremely low and/or variable output voltage
