500mA LED STEP-DOWN CONVERTER
Description
Pin Assignments
The AP8801 is a step-down DC/DC converter designed to drive LEDs with
a constant current. The device can drive up to thirteen LEDs, depending on
?

the forward voltage of the LEDs, in series from a voltage source of 8V to
48V. Series connection of the LEDs provides identical LED currents

resulting in uniform brightness and eliminating the need for ballast
resistors. The AP8801 switches at frequency up to 700kHz. This allows
the use of small size external components, hence minimizing the PCB area
needed.

Maximum output current of AP8801 is set via an external resistor
connected between the V IN and 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 shuts down the output at SW and
SO-8

puts the device into a low-current standby state.
