AP8803
30V 1A BUCK LED DRIVER
Description
The AP8803 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
Pin Assignments
voltage source of 8V to 30V. Series connection of the LEDs provides
identical LED currents resulting in uniform brightness and eliminating
the need for ballast resistors. The AP8803 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 AP8803 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 puts the device into a low-current standby state.
