SLC1012C Datasheet – LED Backlight Driving Boost Switch
SLC1012C overview
The SLC1012C is an LED Backlight Driving Boost Switch made by Fairchild Semiconductor, supplied in a 16 Pin SOIC Type package. The absolute maximum ratings table on this page lists the 6 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the SLC1012C pinout and maximum ratings, with the full datasheet PDF to preview below or download.
The FAN7340 is a single-channel boost controller that integrates an N-channel power MOSFET for PWM dimming using Fairchild’s proprietary planar Double- diffused MOS (DMOS) technology.
The IC operates as a constant-current source for driving high-current LEDs .
It uses Current Mode control with programm able slope compensation to prevent subharmonic oscillation. The IC provides protections including: open-LED protection, over-voltage protection, and direct-short protection for high system reliability.
The IC internally generates a FAULT signal with delay if an abnormal LED string condition occurs. PWM dimming and analog dimming functions can be implemented independently. Internal soft-start prevents inrush current flowing into output capacitor at startup.
