The LM3492 is a two-channel LED driver with an integrated boost converter and fast current regulators. It is designed to drive two separate strings of LEDs with individual dimming capabilities. The device features a wide input voltage range of 4.5V to 65V and supports a boost output up to 65V. It utilizes Dynamic Headroom Control to maximize efficiency and is stable with ceramic and low ESR capacitors without needing loop compensation.
