AL8807B Datasheet | Diodes Incorporated

NEW PRODUCT HIGH EFFICIENCY 36V 1.3A PWM DIMMABLE BUCK LED DRIVER Description The AL8807B is a step-down DC/DC converter designed to drive LEDs with a constant current. The device can drive up to 9 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 AL8807B switches at frequency up to 1MHz with controlled rise and fall times to reduce EMI. This allows the use of small size external ponents, hence minimizing the PCB area needed. Maximum output current of AL8807B is set via an external...
