FAN73402 Datasheet (Fairchild Semiconductor) - LED Backlight Driving Boost Switch

FAN73402, LED Backlight Driving Boost Switch

The FAN73402 is a single-channel boost controller that integrates an N-channel power MOSFET for PWM dimming using Fairchild’s proprietary planar Doublediffused MOSFET (DMOS) technology.

The IC operates as a constant-current source for driving high-current LEDs.

It uses Current Mode control with prog
