Peak Current Mode Boost PWM Controller with Programmable Frequency, external SS and Light Load
Session Titefor popup
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 non-isolated 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. 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, MP3910A 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 MP3910A is available in SOIC8 package.

EV3910A-S-00A Evaluation Kit Peak Current Mode PWM Controller Boost Evaluation Board
The EV3910A-S-00A evaluation board is designed to demonstrate the capabilities of the MP3910A. The MP3910A is a peak current control mode PWM controller that can drives an external MOSFET capable of handling >10A current. It has a typical operational current of 400μA and can accommodate flyback and boost for non-isolated and isolated applications.
While designed for boost applications, the 1A gate driver minimizes the power loss on the external MOSFET while allowing the use of a wide variety of standard threshold devices. In addition, the MP3910A includes pulse-skip mode, which improves the efficiency in light-load or no-load conditions.
The MP3910A is available in an SOIC-8 package.
