The Texas Instruments UC3865DW is an AC DC converter and offline switch IC. It is designed for resonant-mode power supplies, supporting topologies such as Full-Bridge, Half-Bridge, and Push-Pull. This device operates within a voltage range of 10.5V to 22V and a frequency range of 10kHz to 1MHz.
Key features include Soft Start control and internal switches. The UC3865DW is packaged in a 16-SOIC (0.295", 7.50mm Width) case and is designed for surface mount applications. It operates within an ambient temperature range of 0°C to 70°C.
This part is noted as 'NOT RECOMMENDED FOR NEW DESIGNS' by the manufacturer. While it remains available for existing customers, new designs should consider alternate products. The UC3865DW is optimized for the control of Zero Current Switched (ZCS) or Zero Voltage Switched (ZVS) quasi-resonant converters.
