MP6906
DESCRIPTION
The MP6906 is a low-drop diode emulator IC that bines an external switch to replace Schottky diodes in high-efficiency flyback converters. The chip regulates the forward drop of an external switch to about 30m V and switches it off as soon as the voltage bees negative.
The MP6906 provides a SYNC interface to receive an external signal to shut down the gate driver for reliable continuous conduction mode (CCM) operation. A programmable light-load sleep mode reduces the IC’s quiescent current to 150µA. Also, it has a low UVLO level for operation at a lower output without an additional winding. Rail-to-rail output provides higher driving voltage to the external MOSFET.
The MP6906 is available in pact SOIC-8 and TSOT23-6 packages.
