Current Mode PWM Controller 10-Pin MSOP T/R

The MP3910GK-Z 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 MP3910GK-Z can also be used for other topologies including Boost, Forward and Sepic. The 1A gate driver minimizes the power loss of the external MOSFET while allowing the use of a wide variety of standard threshold devices. Additionally, MP3910GK-Z has pulse skipping mode function that improves the efficiency with light load or no load. It also provides hiccup protection for OLP, OVP and SCP condition. The MP3910GK-Z is available in MSOP10 package.
