LTC3218 Datasheet (Linear Technology) - 400mA Single Wire Camera LED Charge Pump

LTC3218, 400mA Single Wire Camera LED Charge Pump

The LTC®3218 is a low-noise, high-current charge pump DC/DC converter capable of driving high current LEDs at up to 400mA from a 2.9V to 4.5V input.

A low external parts count (one ﬂying capacitor, two programming resistors and two bypass capacitors at VIN and CPO) make the LTC3218 ideally suited fo
