# LDD\-1000H (Component)

## Description

DC\-DC LED Driver Module – 1 A constant\-current step\-down \(buck\) LED driver for high\-power LED lighting applications\. Operates from a 9 V to 56 V DC input, delivers a 1000 mA regulated output current, and supports an output voltage up to 52 V DC\. Features up to 97% efficiency, PWM and analog dimming control, short\-circuit protection, overtemperature protection, and high conversion efficiency for low heat generation\. Housed in a compact SIP\-style through\-hole package and specified for operation over a −40°C to \+85°C temperature range\.
