PF7804 - WLED Backlight Driver

Description

The PF7804 is a 70V, 4-channel LED driver which integrates current-programmable power MOSFETs and a boost controller.

The adjustable switching frequency of the boost controller offers the flexibility for the design trade-off between EMI performance and efficiency.

Features

  • Integrated DC/DC Boost Controller.
  • Support Up to 4 LED Strings.
  • Integrated Current Matching MOSFETs.
  • Expandable to Drive More than 4 LED Strings.
  • PWM Dimming & Enable Input.
  • Programmable Output Current.
  • Power Good Signal Output (FLAG).
  • Boost Over Current Protection.
  • Short LED Lamp Protection.
  • Open LED Lamp Protection.
  • Over Temperature Protection.
