Overview

A current-regulated charge pump ideal for powering high brightness LEDs for camera flash applications. The charge pump can be set to regulate two current levels for FLASH and TORCH modes. It incorporates a 1-wire interface to program the flash LED current at 8 levels and flash timeout at 2 levels. It supports PWM dimming to adjust the LED brightness during torch application by simply providing a PWM signal to FLASH pin. It features an ultra low RDSON, and automatically switches modes between 1X and 2X, not only ensuring that LED current does not depend on the forward voltage, but also optimizing the efficiency at the whole power supply and load range. It also features an automatic soft-start mode to limit inrush current, as well as over-temperature, over-voltage and short-circuit protection. It is available in a small 3mm*3mm DFN-10L package and is specified over the -40 °C to +85 °C ambient temperature range.
