The Future of Analog IC Technology
MP3908
Current Mode PWM Controller with Synchronous Secondary Gate Drive
DESCRIPTION
The MP3908 is a flexible current-mode PWM controller optimized for power-supply applications. The MP3908 features resistorprogrammable dead-time control to optimize efficiency for a broad number of different configurations, and a synchronous secondary gate drive. The MOSFET drivers are capable of driving >10A MOSFETs. It has an operational current of typically 270µA and can accommodate off-line, Telecom and non-isolated applications. Under-voltage lockout, soft-start, slope compensation and peak current limiting are all included.
