This engineering report describes a TRIAC dimmable, non-isolated buck-boost LED driver designed to drive a nominal LED voltage string of 38 V at 260 mA from an input voltage range of 90 VAC to 132 VAC ...
This paper presents a novel approach to control a boost PFC AC/DC converter without using any current sensors. Due to the particular structure of the boost PFC AC/DC converter, sensorless control of ...
These advanced PFC boost controller ICs, which manage startup scenarios, minimize the add-on components needed to complete circuit function. Experienced designers know that for many system ...
