Active-clamp & ZVS flyback controllers

Our flybacks feature a dissipative clamp replaced with lossless active clamp, which is used to achieve zero-voltage switching (ZVS).

PWM and flyback controllers

Our fixed-frequency PWM controllers support several power topologies including SEPIC, forward, and many more. Our flyback controllers improve efficiency, minimize standby power, and minimize EMI. 

Offline flyback converters

Our offline flyback converters have a 700-V integrated FET and can be configured as a flyback or a high-voltage buck converter.

Minimize your solution size while maximizing your efficiency

Our latest flyback controllers enable zero-voltage switching (ZVS) and active clamp flyback (ACF) topologies which achieve improved efficiency while increasing power density and shrinking the size of the power supply. ZVS drastically reduces switching losses which in turn enables higher switching frequency capability and reduces the size of the magnetics. ACF also improves on efficiency by replacing the passive clamp with an active clamp, recovering the leakage energy, and delivering it to the output. Finally, integrated features further help reduce the external component count and simplify power supply design.

Ultra-low standby power for low power consumption

Our solutions are capable of offering ultra-low standby power (< 5 mW at no load). This not only achieves but surpasses energy efficiency requirements from the Code of Conduct (CoC) and Department of Energy (DoE) in household goods and appliances. Additionally, ultra-low standby power helps reduce power consumption and extend battery life in HV battery applications such as HEV/EV and battery-back up units.
