General Description
The A8514 is a multi-output white LED driver for small-size LCD backlighting.
It integrates a current-mode boost converter with internal power switch and four current sinks.
The boost converter can drive up to 48 LEDs, 12 LEDs per string, at 80 mA.
Key Features
- 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 p.
