Many appliances today use non-isolated power supply to furnish low output power required to run a micro, LED display, and a few relays or AC switches. This type of power supply has a single rectifier so as to reference the neutral to output ground in order to fire TRIACs or AC switches.

The TPS54350 dc/dc converter is designed to provide up to 3-A output from a nominal 12-V (6-V to 18-V) input voltage source. Rated input voltage and output current range is given in Table 1−1. This evaluation module is designed to demonstrate the small PCB areas that may be achieved when designing with the TPS54350 regulator and does not reflect the high efficiencies that may be achieved when des…

The UCC28600 evaluation module (EVM) is a 120-W off-line quasi-resonant flyback converter providing a 19.4-V regulated output at 6.2 A of load current, operating from a universal ac input.

This user manual describes a high efficiency solution for industrial power supplies with a continuous output power of 150 W and peak power up to 240 W. It takes advantage of the resonant approach to minimize switching losses, resulting in higher than 90% efficiency. The topology is based on half-bridge and operated in a resonant fashion by means of a resonant LC tank, driven by the L6599 dedicate…
