AP8800A

COST EFFECTIVE 28V BUCK 1-W LED DRIVER

Description

Pin Assignments

The AP8800A is a step-down DC/DC converter designed to

drive LEDs with a constant current. The device can drive up

to 7 LEDs, depending on the forward voltage of the LEDs, in

series from a voltage source of 8V to 28V. Series connection

of the LEDs provides identical LED currents resulting in

uniform brightness and eliminating the need for ballast

resistors. The AP8800A switches at frequency up to 600kHz.

This allows the use of small size external components, hence

minimizing the PCB area needed.

V_IN

GND

CTRL

SET

Maximum output current of AP8800A is set via an external

resistor connected between the V_INand SET input pins.

Dimming is achieved by applying either a DC voltage or a

PWM signal at the CTRL input pin. An input voltage of 0.2V

or lower at CTRL switches off the output MOSFET simplifying

PWM dimming.
