The LTM8042 is a complete μModule® (power module) Boost LED Driver specifically designed to drive LEDs up to 1A, while the LTM8042-1 drives up to 350mA. It combines a boost power topology with a unique current loop to operate as a constant-current source. The PWM input provides as much as 3000:1 LED dimming, while 10:1 analog dimming can be accomplished by a single resistor or analog voltage applied to the CTL pin. As with any boost topology, the LTM8042/LTM8042-1 has an uninterrupted current path between its input and output and is thus intolerant to a short-circuit or overload from the output to ground.

Product Detail

Demonstration circuits 1511A-B features the LTM8042-1, which is a complete 350mA µModule LED driver. The demonstration circuit is configured using the boost topology, accepting an input voltage from 3V to 30V and supporting an output up to 32V. The default switching frequency is 950kHz for the DC1511A-B, but can be adjusted by changing the value of the RT resistor. DC1511A is easily configured to support other features, including PWM dimming and analog dimming; It also supports buck-boost mode and buck mode (step-down) topologies.
