Product Details
Product details
UCC 3895 is a phase-shifted PWM controller, which realizes the control of a full-bridge power, the switching of one half-bridge, and the switching of the other half-bridge. The device allows constant frequency pulse width modulation and resonant zero voltage switching to provide high frequency with high efficiency. This part can be used as a voltage-type or current-type controller.
While the UCC 3895 maintains the capabilities of the UC 3875/6/7/8 series and UC 3879, it improves upon the controller family with additional features such as enhanced control logic, adaptive delay sets and shutdown capabilities. Since the device is fabricated using the BCDMOS process, it operates with much less current than bipolar power supplies. The maximum clock frequency of the UCC 3895 is 1 MHz.
Turbo Delay with Programmable Output Adaptive Delay Set Bidirectional Oscillator Synchronous Voltage Mode Peak Current Mode or Average Current Mode Programmable Soft Start Soft Stop Chip Controlled by Single Pin 0% to 100% Duty Cycle 7 MHz Error Amplifier Operation 1 MHz Typical 5 mA operating current at 500 kHz with extremely low 150-A current during UVO.
