400mA Buck/Boost Charge Pump LED Driver

DESCRIPTION

FEATURES

The KB3386 is a current regulated charge pump ideal for

powering high brightness LEDs for camera flash applications.

The charge pump can be set to regulate two current levels for

■ Output Current up to 400mA

■ Up to 94% Efficiency in Torch Mode

■ Automatic Softstart Limits Inrush Current

■ Adjustable FLASH Mode

■ x1 and x2 Automatic Modes for High Efficiency

■ Minimum External Components: No Inductors

■ High Frequency Operation: 2.4 MHz

■ Low 50mV Reference for low Loss Sensing

■ 1+A Shutdown Current

FLASH and TORCH modes. The KB3386 automatically switches

modes between step-up and step-down ensuring that

LED current does not depend on the forward voltage. A low

current sense reference voltage (50mV) allows the use

of small 0603 current sensing resistors. The KB3386 is .

offered in 10-pin DFN package.

■ PWM Dimming Control

■ Automatic Switchover Between Buck/Boost

■ Overvoltage Protection on Output

■ Overcurrent/Temerature Protection

■ Low Ripple and EMI

■ Space Saving 10-pin 3mm x 3mm DFN
