MP3910 Peak Current Mode Boost PWM Controller with Programmable Frequency, The Future of Analog IC Technology External Soft Start, and Light Load Operation DESCRIPTION The MP3910 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 288µA 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, internal regulated supply and slope compensation are all provided to minimize the external component count. While designed for Flyback applications, the MP3910 can also be used for other topologies including Boost, Forward and Sepic.
