LTM8040IV#PBF General Description

The LTM8040 is a fixed frequency 1A step-down DC/DC μModule^® (power module) regulator 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 2.5V to 13V. Unique PWM circuitry allows a dimming range of 250:1, avoiding the color shift normally associated with LED current dimming.

Key Features

Programmable Pulse Width Modulation
Fault-Tolerant Capability
Open-Led Detection and Recovery
Over-Temperature Protection and Recovery

Application

Landscape Accent Lighting
