MP3910

Peak Current Mode Boost PWM Controller with Programmable Frequency, external SS and Light Load

Datasheet

概要

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 non-isolated 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. 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, MP3910 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 MP3910 is available in MSOP10 package.

EV3910-K-00A Evaluation Kit Peak Current Mode PWM Controller Flyback Evaluation Board

The EV3910-K-00A evaluation board is designed to demonstrate the capabilities of the MP3910. The MP3910 is a peak current control mode PWM controller that can drives an external MOSFET capable of handling >10A current. It can accommodate flyback and boost for isolated and non-isolated applications.

While designed for flyback applications, the 1A gate driver minimizes the power loss onthe external MOSFET while allowing the use of a wide variety of standard threshold devices. In addition, the MP3910 includes pulse-skip mode, which improves the efficiency in light-load or no-load conditions. It also provides hiccup protection for OLP, OVP, and SCP conditions.

The MP3910 is available in an MSOP10 package.
