JW1571
Offline Boost PFC CV Controller
Preliminary Specifications Subject to Change without Notice
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.
JW1571 has multi-protection functions which largely enhance the safety and reliability of the system, including VCC UVLO, CS over voltage protection, FB over voltage protection and over temperature protection.
