60V 1A STEP-DOWN LED DRIVER

Description

Pin Assignments

The DIODES^TMAL8862 is a step-down DC/DC converter designed to

drive LEDs with a constant current. The AL8862 operates with an

input supply voltage from 5V to 60V and provides an externally-

adjustable output current up to 1A. Series connection of the LEDs

provides identical LED currents, resulting in uniform brightness and

eliminating the need for ballast resistors. The AL8862 switches at

frequencies up to 1MHz. This allows the use of smaller-sized external

components, hence minimizing the PCB size.

The AL8862 integrates the power switch and a high-side output

current-sensing circuit. Maximum output current of the AL8862 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. The soft-start time can be adjusted

using an external capacitor from the CTRL pin to ground. An input

voltage of 0.3V or lower at CTRL pin will shut down the power switch.
