This article introduces the LTM8040 LED driver from Linear Technology. The driver features a high level of integration and can drive up to 1A of LED strings. It supports both analog and PWM dimming and has a built-in 14V output voltage clamp to prevent damage in the event of an accidental open LED string.
The LTM8040 is a module LED driver designed to integrate all driver circuitry, including the inductor, into a single surface mount package. It features both analog and PWM dimming capabilities, allowing for a dimming range of 250:1. The device includes an open LED string protection feature with a built-in 14V output voltage clamp.
The device can drive up to 1A through a string of LEDs.
It accepts an input voltage ranging from 4V to 36V.
The module measures 15mm x 9mm x 4.32mm.
