LM3630A - High-Efficiency Dual-String White LED Driver

Description

The LM3630A is a current-mode boost converter which supplies the power and controls the current in up to two strings of 10 LEDs per string.

Programming is done over an I2C-compatible interface.

The maximum LED current is adjustable from 5 mA to 28.5 mA.

Features

  • 1 Drives up to 2 Strings of 10 Series LEDs.
  • Wide 2.3-V to 5.5-V Input Voltage Range.
  • Up to 87% Efficient.
  • 8-bit I2C-Compatible Programmable Exponential or Linear Brightness Control.
  • PWM Brightness Control for CABC Operation.
  • Independent Current Control per String.
  • True Shutdown Isolation for LEDs.
  • Internal Soft-Start Limits Inrush Current.
  • Adaptive Headroom.
  • Programmable 16-V/24-V/32-V/40-V Overvoltage Prot.
