ABLIC’s single-chip, battery-level sensor/display driver saves power and simplifies the design of cordless tools and other portable products.

This study proposes a novel light-emitting diode (LED) driver circuit that stabilizes the lighting output without a photodiode. The LED driver circuit is composed of a self-alignment circuit to ...

An auto-zero-voltage-switching (ZVS) quasiresonant LED driver with gallium nitride (GaN) FETs for general lighting applications is presented. The proposed LED driver switches at high frequency to ...
