LTC3216 - 1A Low Noise High Current LED Charge Pump With Independent Torch/Flash Current Control

The LTC3216 is a low noise, high current Charge Pump DC/DC converter designed to power high current LEDs The part includes an accurate programmable current source capable of driving loads up to 1A from a 2.9V to 4.4V input. Low external parts count (two flying capacitors, two programming resistors and two bypass capacitors at VIN and CPO) make the LTC3216 ideally suited for small, battery-powered applications.
Built-in soft-start circuitry prevents excessive inrush current during start-up. High switching frequency enables the use of small external capacitors. Independent high and low current settings are programmed by two external resistors. Shutdown mode and current output levels are selected via two Logic inputs.
An ultralow dropout current source maintains accurate LED current at very low ILED voltages. Automatic mode switching optimizes efficiency by monitoring the voltage across the LED current source and switching modes only when ILED dropout is detected. The LTC3216 is available in a small 3mm x 4mm 12-Lead DFN package.
