LTC3214 Datasheet 500ma Camera Led Charge Pump

Manufacturer: Linear Technology (now Analog Devices)

Overview: LTC3214 500mA Camera LED Charge Pump.

General Description

The LTC®3214 is a low noise, high current charge pump DC/DC converter capable of driving high current LEDs at up to 500mA from a 2.9V to 4.5V input.

Low external parts count (two flying capacitors, one programming resistor and two bypass capacitors at VIN and CPO) make the LTC3214 ideally suited for small, battery-powered applications.

Built-in soft-start circuitry prevents excessive inrush current during start-up.
