AP8801M8G-13, Драйвер светодиода, 1 выход, понижающий, 8В-48В вход, частота коммутации 700кГц, 0.5А выход, MSOP-8

The AP8801M8G-13 is a step-down DC-to-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 8 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 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.

• High efficiency up to 92%
• LED driving current up to 500mA
• PWM/DC input for dimming control
• Built-in output open-circuit protection
