IS31BL3233A - 1.5A FLASH/TORCH LED DRIVER

General Description

The IS31BL3233A is the ideal power solution for high-power flash LEDs used with cell phone camera modules or digital still cameras.

It is a highly integrated step up DC-DC converter with very high switching frequency, fixed at 2MHz, providing a very small total solution for portable photo flash.

Key Features

  • are built into the IS31BL3233A, including cycle-by-cycle input current limit protection, output over-voltage protection, LED fault (open or short) protection and thermal shutdown protection. The IS31BL3233A is available in a RoHS compliant DFN-14 (2mm × 3mm) package.

IS31BL3233A 2MHz, 1.5A FLASH/TORCH LED DRIVER Preliminary Information September 2014 GENERAL DESCRIPTION The IS31BL3233A is the ideal power solution for high-power flash LEDs used with cell phone camera modules or digital still cameras. It is a highly integrated step up DC-DC converter with very high switching frequency, fixed at 2MHz, providing a very small total solution for portable photo flash. The IS31BL3233A has separate Flash Mode and Torch Mode enable pins for maximum flexibility. The Flash Mode and Torch Mode LED current is programmed by external resistors respectively, making the flash LED solution simple to control. If both enable pins are at logic high, the LED current will be programmed by the Torch Mode setting resistor.
