LTM8040 Datasheet 1A Module LED Driver

Manufacturer: Linear Technology (now Analog Devices)

Overview: Electrical Specifications Subject to Change LTM8040 36V, 1A µModule LED Driver www.datasheet4u.

General Description

The LTM®8040 is a fixed frequency 1A step-down DC/DC μModule™ designed to operate as a constant current source.

Internal circuitry monitors the output current to provide accurate current regulation, which is ideal for driving high current LEDs.

High output current accuracy is maintained over a wide current range, from 35mA to 1A, allowing a wide dimming range over an output voltage range of 2.4V to 13V.

Key Features

  • True Color PWM™ Delivers Constant Color with 400:1 Dimming Ratio Wide Input Range: 4V to 36V Up to 1A LED Current Adjustable Control of LED Current High Output Current Accuracy is Maintained Over a Wide Range from 35mA to 1A Open LED and Short-Circuit Protection Grounded Cathode Connection Small Footprint, Low Profile (15mm × 9mm × 2.82mm) Surface Mount LGA Package.
