LED驱动电流高达1A优于5％的精度效率高达98 ％工作输入电压从6V至30V高开关频率高达1MHzPWM / DC输入的调光控制内置输出开路保护SOT25
Description
The AL8805 is a step-down DC/DC converter designed to drive LEDs
with a constant current. The device can drive up to 8 LEDs,
depending on the forward voltage of the LEDs, in series from a
voltage source of 6V to 36V. Series connection of the LEDs provides
identical LED currents resulting in uniform brightness and eliminating
the need for ballast resistors. The AL8805 switches at frequency up to
1MHz. This allows the use of small size external components, hence
minimizing the PCB area needed.
Maximum output current of AL8805 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 0.4V or lower at CTRL switches off the output
MOSFET simplifying PWM dimming.
