AP8803WTG-7

The AP8803WTG-7 is a Buck LED Driver 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 8 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 AL8803 is set via an external resistor connected between the VIN 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.

• LED driving current up to 1A
• High efficiency up to 92%
• Operating input voltage up to 30V
• High switching frequency up to 700kHz
• PWM/DC input for dimming control
• Built-in output open-circuit protection
