A8502 Datasheet High Efficiency Fault Tolerant Led Driver

Manufacturer: Allegro MicroSystems

Overview: A8502 Wide Input Voltage Range, High Efficiency Fault Tolerant LED.

General Description

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.

The boost converter can drive up to 24 LEDs, 12 LEDs per string, at 120 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.
