LTM8042 - uModule Boost LED Driver and Current Source

General Description

The LTM®8042 is a complete µModule® 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.

Key Features

  • n True Color PWM™ with 3000:1 Dimming Ratio n Operates in Boost, Buck Mode or Buck-Boost Mode n Wide Input Voltage Range: Operation from 3V to 30V Transient Protection to 40V n Gate Driver for Optional PWM Dimming with P-channel MOSFET n Adjustable Frequency: 250kHz to 2MHz n Constant-Current and Constant-Voltage Regulation n Low Shutdown Current:.
