MP6903

Fast Turn-off Intelligent Controller

The Future of Analog IC Technology

DESCRIPTION

FEATURES

The MP6903 is a low-drop diode emulator that,

combined with an external switch, replaces

Schottky diodes in high-efficiency LLC

converters. The chip regulates the forward drop

of an external switch to about 70mV and

switches it off as soon as the voltage goes

negative. MP6903 has a light-load sleep mode

that reduces the quiescent current to < 300µA.



Works with Standard and Logic-Level FETS

Compatible with Energy Star, 1W Standby

Requirements



V_DDRange from 8V to 24V

Fast Turn-Off: Total Delay of 20ns

Max 400kHz Switching Frequency

<300µA Quiescent Current in Light Load

Mode



Supports DCM, CCM and CrCM Operation

Supports High-Side and Low-Side

Rectification



Power Savings of Up to 1.5W for a Typical

Notebook Adapter

APPLICATIONS



Industrial Power Systems

Distributed Power Systems

Battery Powered Systems

LLC Converters
