Description
The AP8800 is a step-down DC/DC converter designed to
drive LEDs with a constant current. The device can drive up
to seven 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 eliminates the need for
ballast resistors. The AP8800 switches at frequency up to
0.6MHz. This allows the use of small size external
components, hence minimizing the PCB area needed.
Maximum output current of AP8800 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.
