SLC1012C Datasheet | Fairchild Semiconductor

Features - Single-Channel Boost LED Switch - Internal Power MOSFET for PWM Dimming: RDS(on) = 3.4 Ω at VGS=10 V, BVDSS=400 V - Current Mode PWM Control - Internal Programmable Slope pensation - Wide Supply Voltage Range: 10 V to 35 V - LED Current Regulation: ±1% - Programmable Switching Frequency - Analog and PWM Dimming - Wide Dimming Ratio: On Time=10 µs to DC - Cycle-by-Cycle Current Limiting - Thermal Shutdown: 150°C - Open-LED Protection (OLP) - Over-Voltage Protection (OVP) - Over-Current Protection (OCP) - Error Flag Generation (for External Load Switch) - Internal Soft-Start - 16-Lead SOIC Package Description 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. 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. Applications - LED Backlight for LCD TV - LED Backlight for LCD Monitor - LED Lighting Ordering Information Part Number FAN7340MX Operating Temperature Range -40°C to +125°C Package 16-Lead, Small-Outline Integrated Circuit (SOIC) Packaging Method Tape & Reel © 2013 Fairchild Semiconductor Corporation FAN7340 - 1.0.1 .f airchildsemi.
