Product Overview

The LTM8040EV#PBF is a fixed frequency 1A step-down DC/DC µModule® 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 2.5 to 13V. Unique PWM circuitry allows a dimming range of 250:1, avoiding the colour shift normally associated with LED current dimming. With its wide input range of 4 to 36V, the LTM8040 regulates a broad array of power sources, from 4-cell batteries and 5V logic rails to unregulated wall transformers, lead acid batteries and distributed power supplies.
  • 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 LED cathode connection
