The Future of Analog IC Technology MP3910A Peak Current Mode Boost PWM Controller with Programmable Frequency, External Soft Start Light Load Operation, and SOIC8 Package DESCRIPTION The MP3910A is a Peak Current Mode PWM controller that can drive an external MOSFET capable of handling more than 10A current. It has a typical operational current of 400µA and can accommodate flyback, boost for nonisolated and isolated applications. Current mode control provides inherently simple loop compensation and cycle-by-cycle current limit. Under-voltage lockout, soft-start and slope compensation are all provided to minimize the external component count. While designed for Flyback applications, the MP3910A can also be used for other topologies including Boost, Forward and Sepic.
