Overview
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-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 c...
