General Description

The JW®1571 is a constant voltage controller with high voltage accuracy which applies to single stage boost power factor correction (PFC) applications.

Constant on time control strategy ensures high power factor, and the input voltage detection circuit is not needed, which simplifies the system design and saves the loss.

Critical conduction mode operation reduces the switching losses, improves the EMI performance and largely increases the efficiency.
