This is a reference design for an LED display-backlight driver. The design uses a boost power supply with adaptive feedback for efficiency and linear current sinks for a high dimming ratio (2000:1).

This is a design example report of a 12 W, high power factor, non-isolated buck-boost, TRIAC dimmable LED driver employing LYTSwitch™-4 LYT4322E. The design is intended for A19 LED driver application.

Powering up to seven white LEDs, the MAX8847 and MAX8848 backlight drivers employ a negative-charge-pump architecture to eliminate in-line resistance from the battery to the LEDs. As a result, mode ...
