JW1964C Datasheet | JoulWatt Technology

DESCRIPTION The JW1964B/JW1964C/JW1964D (JW1964X series) is a constant voltage controller with high voltage accuracy which applies to single stage boost power factor corrected(PFC) applications. The 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. The critical conduction mode operation reduces the switching losses, improves the EMI performance and increases the efficiency. JW1964X series has multi-protection functions which largely enhance the safety and reliability of the system, including VCC UVLO, ISP over voltage protection, open feedback protection, FB over voltage protection and over-temperature protection. pany’s Logo is Protected, “JW” and “JOULWATT” are Registered Trademarks of Joulwatt Technology Co., Ltd.
