SLC1012C - LED Backlight Driving Boost Switch

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.

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 Compensation.
  • 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).
