A8511 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 plete the backlighting design criteria. The A8511 integrates FETs for a boost converter as well as four 150 mA current sinks, offering a plete integrated solution at HB LED current levels.
A8511 Key Features
- Four LED sinks rated for 150 mA each (600 mA total)
- Boost converter with integrated 40 V DMOS switch and
- Internal bias supply for single-supply operation (VIN= 6.8 to 21 V)
- 3.5 µA shutdown current-limits battery drain
- PWM dimming with LED PWM duty cycle control
- 4000:1 dimming range
- Extensive fault mode protection schemes
