Reference design
Automotive 400-W, 48-V Battery Input, 12-V Output Power Reference Design
This reference design is an automotive, 400-W, phase-shifted full-bridge converter which generates the 12-V output from a 48-V car battery. The enhanced phaseshifted full-bridge controller implements programmable delays which ensure zero voltage switching (ZVS) over a wide range of operating (...)
Reference design
54-VDC input, 12-V 42-A output half-bridge reference design
This 12-V, 42-A output half-bridge reference design is for bus converters in wired networking campus and branch switches. The design features high efficiency and various fault protections (over-current and short-circuit). The design provides an efficiency comparison using 3 kVRMS basic and (...)
Reference design
2-kW industrial AC/DC battery charger reference design with 92% full-load efficiency
This reference design is a module that can be set as standard power supply or a battery charger. The output voltage ranges from 0 V to 32 V at a maximum current of 62.5 A. It consists of four boards, a boost PFC, a phase shift full bridge, a small daughter board (hosting the microcontroller), and (...)
