SLC1012C Overview
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 programmable slope pensation to prevent subharmonic oscillation.
