Regardless of the end-user, they must meet national and international standards (including 80 PLUS®, ErP Lot 6, and Energy Star) for product efficiency, as well as power density, reliability, and safety at appropriate price Requirements.
In order to find the best application solution, designers must choose the most effective power topology (flyback, boost, or quasi-resonance) or implementation (based on monolithic integrated circuits or discrete power switches and controllers), or even decide to use advanced Digital circuit implementation. No matter what their choice is, the right product is the key to meeting their specific design goals.
The broad product portfolio includes highly integrated AC-DC converters and controllers, DC-DC converters, silicon, and silicon carbide (SiC) power MOSFETs and rectifiers, IGBTs and protection ICs, linear voltage regulators, battery management (including battery Charger and wireless charger), specially designed digital control.
In a typical AC-DC switching power supply (SMPS), the AC power supply enters the power factor correction (PFC) stage after rectification and filtering. Then, it is delivered to a DC load with the required voltage and current ratings through high-frequency modulation techniques (sometimes in order to reduce the size of transformers and inductive components to make them exceed 1 MHz frequency).
