Everyone loves a full-wave bridge rectifier, but there’s no denying that they aren’t 100% efficient due to the diode voltage drop. Which isn’t to say that with some effort we cannot create an ideal ...

Texas Instruments Incorporated introduced two high-efficiency PWM power supply controllers with integrated, programmable-delay synchronous rectifier control outputs and pre-bias start-up circuitry.

The ISL78223 is a high-performance zero-voltage switching(ZVS) full-bridge PWM controller. It achieves ZVS operation by driving the upper bridge FETs at a fixed 50% duty cycle while the lower bridge ...

The UCC28250 and UCC28950 green controllers simplify design and boost efficiency in high-density isolated power supplies for telecommunications, server and industrial systems. The devices support ...
