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. The two LED output sinks can be shorted
together externally for higher power single flash LEDs,
up to 1.5A continuous LED current. Thermal regulation
is integrated in Flash Mode to limit the IC’s temperature
and continuously provide the maximum allowed output
current.
Various protection 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.
