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

General Description

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.

Key Features

  • n Charge Pump Provides High Efficiency with Automatic Mode Switching n Multimode Operation: 1x, 1.5x, 2x n Four Low Dropout LED Outputs n Up to 600mA Total Output Current n Independent Torch and Flash ISET and Enable Pins n Low Noise Constant Frequency Operation.
  • n PWM Brightness Control via the EN2 Pin n Low Shutdown Current: 4μA n Internal Soft-Start Limits Inrush Current During Start-Up and Mode Switching n Open/Short LED Protection n No Inductors n (3mm x 3mm) 16-Lead QFN Plastic Package.
