FAN7340 - LED Backlight Driving Boost Switch
The FAN7340 is a single-channel boost controller that integrates an N-channel power MOSFET for PWM dimming using Fairchild’s proprietary planar Doublediffused MOS (D MOS) technology.
The IC operates as a constant-current source for driving high-current LEDs.
It uses Current Mode control with program
