MPS Releases New Fast Turn-off Flyback Synchronous Rectifier

By Rob GrayFebruary 21, 2017

Monolithic Power Systems (MPS), a leading international power solutions company headquartered in San Jose, California, launches its new Fast Turn-off Flyback Synchronous Rectifier MP6907 that supports CCM, DCM and QR Operation Modes.

The MP6907 is a low-drop diode emulator controller IC, which when combined with an external MOSFET can replace the Schottky diodes in high-efficiency flyback converters.

Monolithic’s new Fast Turn-off Flyback Synchronous Rectifier regulates the forward drop of an external switch up to 70 mV and automatically switches off as soon as the voltage becomes negative.

The MP6907, integrated with a programmable light-load sleep mode, can reduce the IC’s quiescent current up to ~150μA.

In addition, the device also provides an SYNC interface that shuts down the gate driver in order to enable a reliable continuous conduction mode (CCM) operation.

Prime Features of MP6907 Synchronous Rectifier

MP6907 incorporates the following features - 

  • Works with 12V Standard and 5V Logic Level MOSFETs
  • Compatible with Energy Star 1W Standby Requirements
  • Fast Turn-Off Total Delay of 25ns
  • 4.2V~35V Wide VDD Operating Range
  • ~150μA Quiescent Current in Light-Load Mode(1)
  • Supports CCM, DCM, and Quasi-Resonant Operation
  • SYNC Interface for CCM Operation
  • Supports High-Side and Low-Side Rectification
  • Power Savings of up to 1.5W in a Typical Notebook Adapter
  • Available in SOIC8 and TSOT23-6 Packages
