Product Description

The MP6960 is a synchronous rectified controller for a high-efficiency flyback converter circuit. The controller has integrated voltage and current regulators for the secondary side of the converter, making it suitable for battery charging and as a secondary controller for switching regulator systems. The MP6960 regulates the forward drop of an external switch to about 70mV and switches it off as soon as the voltage goes negative. It also has a light-load sleep mode to reduce the quiescent current to <300?. The MP6960 also compares the DC voltage and the current level at the output of a switching power supply to the voltage reference and current limitation, respectively. It provides feedback through an opto-coupler to the PWM controller IC at the primary side. The MP6960 is available in an SOIC8 package.
