A8511 - 4-Channel x 150 mA WLED/RGB Driver

General Description

The A8511 is a multioutput WLED/RGB driver for backlight-ing medium-size displays.

It is a fully integrated high-brightness (HB) LED driver solution that does not require external power devices to complete the backlighting design criteria.

Key Features

  • Four LED sinks rated for 150 mA each (600 mA total).
  • Boost converter with integrated 40 V DMOS switch and OVP.
  • load-dump protection.
  • 600 kHz to 2.2 MHz switching frequency.
  • ability to operate above the AM band.
  • Internal bias supply for single-supply operation (VIN= 6.8 to 21 V).
  • 3.5 µA shutdown current.
  • limits battery drain.
  • Active current sharing between LED strings for 0.8% current matching and 0.7% accuracy.
  • PWM dimming with LED PWM dut.
