Description
The A8511 is a multioutput WLED/RGB driver for backlighting 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. The A8511 integrates FETs for a boost converter as well as four 150 mA current sinks, offering a complete integrated solution at HB LED current levels. LED channels can be tied together for up to 600 mA sink capability. It can work from a single power supply of 6.8 to 21 V and withstand up to 40 V. The boost converter is a constant frequency, current-mode converter.
Features and Benefits
? 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 duty cycle control
? 4000:1 dimming range
? Extensive fault mode protection schemes:
? Shorted LED protection against misconnected loads—with true output disconnect
? Open LED disconnect protects against LED failures
? External thermistor sensing to limit LED temperature
? Output overvoltage protection (OVP): 19.5 V default can be adjusted as high as 38 V
? Open Schottky and open OVP resistor protection against external component failure
? Input under- and overvoltage protection (UVLO and OVLO) against VIN variation
? Boost current limit, output short circuit limit, overtemperature protection (OTP), and soft start
Applications include:
? GPS navigation systems
? Automotive infotainment
? Back-up camera displays
? Cluster backlighting
? Portable DVD players
? Industrial LCD displays
