MP3910

Peak Current Mode

Boost PWM Controller with Programmable Frequency,

External Soft Start, and Light Load Operation

The Future of Analog IC Technology

DESCRIPTION

FEATURES



5V to 35V Supply Voltage Range⁽¹⁾

1A 12V MOSFET Gate Driver

External Soft-Start

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.

Pulse Skipping Operation with Light Load

Programmable

(30kHz-to-400kHz)

Switching

Frequency

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.



Frequency Synchronizable from 80kHz-to-

400kHz

Cycle-by-Cycle Current Limit

Over Voltage Protection

Short Circuit Protection

Over Temperature Protection

Available in an MSOP10 Package



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.

APPLICATIONS



Telecom Isolated Power Supplies

Brick Modules

Off-line Controller
