Implementing cost-effective, robust power factor correction with the NCP1606

Posted: 03 Dec 2009     Print Version  Bookmark and Share

Keywords:NCP1606 pre-converter  design implementation pre-converter  power factor correction 

The NCP1606 is a voltage mode power factor correction (PFC) controller designed to drive cost-effective pre-converters to meet input line harmonic regulations. The device operates in critical conduction mode (CRM) for optimal performance in applications up to about 300W. Its voltage mode scheme enables it to obtain unity power factor without the need for a line sensing network. The output voltage is accurately controlled with a built in high precision error amplifier. The controller also implements a comprehensive array of safety features for robust designs.

This application note describes the design and implementation of a 400V, 100W, CRM boost PFC pre-converter using the NCP1606. The converter exhibits high power factor, low standby power dissipation, good active mode efficiency and a variety of protection features.
