概觀

The IS31BL3231 is a current-regulated charge pump and ideal for powering high brightness LEDs for camera flash and torch applications. The charge pump can be set to regulate two current levels for FLASH and TORCH modes. The IS31BL3231 automatically switches between linear and boost modes ensuring that LED current does not depend on the LED forward voltage. IS31BL3231 provides low cost, space saving solution for driving LED. It also integrates thermal and short circuit protection function. IS31BL3231 is available in DFN-10 (3mm × 3mm). It operates from 2.7V to 5.5V over the temperature range of -40°C to +85°C.
