FAN7340MX - LED Backlight Driving Boost Switch

Download the FAN7340MX datasheet PDF. This datasheet also covers the FAN7340 variant, as both devices belong to the same led backlight driving boost switch family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key 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).
