● DESCRIPTIO High Efficiency Operation: 1x, 1.5x or 2x Boost Modes with Automatic Mode Switching Ultralow Dropout ILED Current Control Output Current up to 700mA Low Noise Constant Frequency Operation* Wide VIN Range: 2.9V to 4.4V Open/Shorted LED Protection LED Disconnect in Shutdown Low Shutdown Current: 2.5µA 4% LED Current Programming Accuracy Automatic Soft-Start Limits Inrush Current No Inductors Tiny Application Circuit (All Components <1mm Profile) 3mm × 3mm 10-Lead DFN Package The LTC®3215 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 700mA from a 2.9V to 4.4V input. Low external parts count (two flying capacitors, one programming resistor and two bypass capacitors) makes the LTC3215 ideally suited for small, batterypowered applications. Built-in soft-start circuitry prevents excessive inrush current during start-up.
