LTM8042-1 - uModule Boost LED Driver and Current Source

Download the LTM8042-1 datasheet PDF. This datasheet also covers the LTM8042 variant, as both devices belong to the same umodule boost led driver and current source family and are provided as variant models within a single manufacturer datasheet.

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:.
