MP3910A

Peak Current Mode Boost PWM Controller

with Programmable Frequency, External Soft Start

Light Load Operation, and SOIC8 Package

The Future of Analog IC Technology

DESCRIPTION

FEATURES



9V to 14V Supply Voltage Range

1A MOSFET Gate Driver

External Soft-Start

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.

Pulse Skipping Operation with Light Load

Programmable

Switching

Frequency

(30kHz-to-400kHz)



Cycle-by-Cycle Current Limit

Over Voltage Protection

Short Circuit Protection

Over Temperature Protection

Available in SOIC8 Package

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.

APPLICATIONS



Telecom Isolated Power Supplies

Brick Modules

Off-line Controller

General Step Up Applications

PoE Powered Devices
