UC3854DWTR General Description

With a wide operating range suitable for single-phase and three-phase systems with varying line voltages (75 V to 275 V) and frequencies (50 Hz to 400 Hz), the UC3854DWTR offers flexibility and adaptability to different power system requirements. Its low starting supply current further reduces the load on the power supply circuitry, making it a reliable and efficient solution for power factor correction needs. Available in different packaging options, including 16-pin plastic and ceramic dual in-line packages, as well as various surface-mount packages, the UC3854DWTR caters to diverse design preferences and application scenarios

Key Features

Rapid Start-Up and Recovery Time
Soft-Stop Functionality
High Frequency PWM Modulation
Low EMI Radiation Emissions
