LT3216 1A Low Noise High Current LED Charge Pump

LTC3216 1A Low Noise High Current LED Charge Pump with Independent Torch/Flash Current Control DESCRIPTIO The LTC®3216 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-.
