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. Unique PWM circuitry allows a dimming range of 400:1, avoiding the color shift normally associated with LED current dimming.
