A8502
Overview
The A8502 is a multi-output white LED driver for small-size LCD backlighting. It integrates a current-mode boost converter with internal power switch and two current sinks.
- AEC-Q100 qualified
- Wide input voltage range of 5 to 40 V for start/stop, cold crank and load dump requirements
- Fully integrated LED current sinks and boost converter with 60 V DMOS
- Sync function to synchronize boost converter switching frequency up to 2.3 MHz, allowing operation above the AM band
- Excellent input voltage transient response
- Single resistor primary OVP minimizes VOUT leakage
- Internal secondary OVP for redundant protection
- LED current of 120 mA per channel
- Drives up to 12 series LEDs in 2 parallel strings
- 0.7% to 0.8% LED to LED matching accuracy
