LTC3217 Datasheet (Linear Technology) - 600mA Low Noise Multi-LED Camera Light Charge Pump

LTC3217, 600mA Low Noise Multi-LED Camera Light Charge Pump

The LTC®3217 is a low noise charge pump DC/DC converter designed to power four high current LEDs.

The LTC3217 requires only four small ceramic capacitors and two current set resistors to form a complete LED power supply and current controller.

Built-in soft-start circuitry prevents excessive inrush
