Electronic equipment and power supplies without any active or passive power factor correction (PFC) circuits have an input current waveform which has a poor power factor and high harmonic distortion.

Power supply ICs are necessary parts in a power supply design. This tutorial will provide the steps towards choosing the appropriate IC for a given application. It differentiates the three most common ...

The HiperTFS™-2 family of ICs from Power Integrations combine two-switch-forward and flyback power-supply controller ICs with integrated high-voltage MOSFETs. This high level of integration saves more ...

Power Integrations has introduced a 1,250V GaN version of its Innoswitch family of off-line constant-voltage constant-current quasi-resonant fly-back switcher ICs, making the options: 725V silicon, ...

Switching power supply chips from firms such as Power Integrations Inc. (San Jose, Calif.), Fairchild Semiconductor International (San Jose, Calif.) and STMicroelectronics Inc. (Lexington, Mass.) ...
