PF7703A - Expandable WLED Backlight Driver

Download the PF7703A datasheet PDF. This datasheet also covers the PF7700A variant, as both devices belong to the same expandable wled backlight driver family and are provided as variant models within a single manufacturer datasheet.

Description

The PF7700A and PF7703A are the 2nd generation products of PF7700 and PF7703.

Compared with PF7700 and PF7703, the voltage rating of integrated current sources is improved to 70V and the GM circuit is also modified to minimize the required value of external compensation capacitor.

Features

  • Compatible with AC/DC or DC/DC Power Stage.
  • Current Drive of LED String Up to 240mA (1).
  • Integrated 70V MOSFET.
  • Expandable for Driving Different Size of Panels.
  • PWM Dimming.
  • Programmable Sinking Current.
  • SLP (Short LED Lamp Protection).
  • OLP (Open LED Lamp Protection).
  • OTP (Over Temperature Protection).
  • Support Local Dimming Control.
  • Enable Input (PF7700A Only).
  • FLAG Signal for Status Indicator (PF7703A Only).
