A8513 Détails du produit

Description
The A8513 is a single-output white LED (WLED) driver for LCD backlighting. It integrates a current-mode boost converter with an internal power switch and one current sink. The A8513 can operate from a single power supply from 4.5 to 40 V, to accommodate start/stop, cold crank, and load dump requirements. A 2 MHz boost converter switching frequency allows the A8513 to operate above the AM radio band.

Features and Benefits
• AEC-Q100 Qualified
• Wide input voltage range of 4.5 to 40 V for start/stop, cold crank and load dump requirements
• Boost converter switching frequency up to 2 MHz, allowing operation above the AM band
• Excellent input voltage transient response
• Internal secondary OVP for redundant protection
• Fully integrated LED current sink and boost converter with 60 V DMOS FET
• Maximum LED current of 150 mA
• Drives up to 14 series LEDs
• Single EN/PWM pin interface for PWM Dimming and Enable function
• 5000:1 PWM dimming at 200 Hz
• Fault flag pin to alert the controller to a myriad of possible fault conditions
• Protection Features:
   ▫ Shorted output
   ▫ Open or shorted LED pin
   ▫ Output undervoltage and overvoltage
   ▫ Input undervoltage
   ▫ Shorted boost switch or inductor
   ▫ Shorted ISET resistor
   ▫ Open boost Schottky
   ▫ Overtemperature

Applications:
• LCD backlighting for:
   ▫ Automotive infotainment
   ▫ Automotive cluster
   ▫ Automotive center stack
   ▫ Industrial LCD displays
   ▫ Portable DVD players
▫ Flatbed Scanners
▫ LED Lighting
