DESCRIPTION

FEATURES

The A8167A-020 is a step-up DC/DC converter

specifically designed for driving white LEDs with a

constant current. The internal MOSFET can

support up to 10 White LEDs for backlighting and

OLED power application, and the internal soft start

function can reduce the inrush current. The

A8167A-020 uses current mode, fixed frequency of

approximately 1.0MHz architecture to regulate the

LED current through an external current sense

resistor. The low feedback voltage of 200mV can

minimize power dissipation.
