Краткое описание:
High Contrast 2-Channel Individual Dimmable LED Driver with Boost Converter
Дополнительная информация
The LM3492HC is a multi-channel LED driver that integrates a boost converter and a two-channel current regulator. It is designed to drive two individually dimmable LED strings with a maximum total power of 15W and an output voltage up to 65V. The device features a projected-on-time control method that provides fast transient response without the need for loop compensation. It supports a 10000:1 contrast ratio with a 300ns minimum pulse width and includes dynamic headroom control to maximize efficiency.
