LM3560 - Synchronous Boost Flash Driver

Datasheet Summary

Description

The LM3560 is a 2-MHz fixed frequency synchronous boost converter with two 1000-mA constant current drivers for high-current white LEDs.

The dual highside current sources allow for grounded cathode LED operation and can be tied together for providing flash currents at up to 2 A through a single LED.

Features

  • 1 Dual High-Side Current Sources Allow for Grounded Cathode LED Operation.
  • Accurate and Programmable LED Current from 31.25 mA to 2 A.
  • Independent LED Current Source Programmability.
  • Up to 90% Efficient.
  • Ultra-Small Solution Size: < 26 mm2.
  • Four Operating Modes: Torch, Flash, Privacy Indicate, and Message Indicator.
  • 4-Bit ADC for VLED Monitoring.
  • LED Thermal Sensing and Current Scale-Back.
  • Hardware Flash and Torch E.
