Half-bridge drivers – Design & development

360W phase-shift full-bridge resonant LLC with high-side, low-side driver

This design's operating mode can replace PWM operating mode in LLC, improving efficiency significantly in light-load.

400-W high-efficiency battery charger for 36V power tools

This design charges a wide range of batteries in the voltage range of 20-40V and is ideal for 10-cell Li-ion battery packs with operating efficiency of 96%.

1/8 brick isolated DC/DC Telecom power module with PWM control

This design features 95% peak efficiency, pre-bias start-up, over temperature protection and over-current protection.
