LTC3214
500mA Camera
LED Charge Pump
FEATURES DESCRIPTION n The LTCВ®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. n Low Noise Constant Frequency Operation
High Efficiency: Up to 94%
Multi-Mode Operation: 1x, 1.5x or 2x Boost Modes
Automatic Mode Switching
High Output Current: Up to 500mA
