    Check for Samples: UCC1895, UCC2895, UCC3895 FEATURES DESCRIPTION The UCC3895 is a phase-shift PWM controller that
    implements control of a full-bridge power stage by
    phase shifting the switching of one half-bridge with
    respect to the other. The device allows constant
    frequency pulse-width modulation in conjunction with
    resonant zero-voltage switching to provide high
    efficiency at high frequencies. The part is used either
    as a voltage-mode or current-mode controller. 1 Programmable-Output Turnon Delay

    Bidirectional Oscillator Synchronization
    Voltage-Mode, Peak Current-Mode, or Average
    Current-Mode Control
    Programmable Softstart, Softstop and Chip
    Disable via a Single Pin
    0% to 100% Duty-Cycle Control
    7-MHz Error Amplifier
    Operation to 1 MHz
    Typical 5-mA Operating Current at 500 kHz
    Very Low 150-ОјA Current During UVLO APPLICATIONS While the UCC3895 maintains the functionality of the
    UC3875/6/7/8 family and UC3879, it improves on that
    controller family with additional features such as ...

    UCC3895 CD Output Asymmetric Duty Cycle Operation
    A small number of current-mode applications using non?synchronous output stages have experienced asymmetric pulse widths on the OUTC and OUTD outputs of the UCC3895. Applications using synchronous rectification and/or voltage mode control typically do not experience this anomaly. For the cost of a single resistor, a simple fix allows reliable and stable operation of the UCC3895.

    UCC2895 Layout and Grounding Recommendations
    The UCC2895 family of Phase Shifted Full Bridge Power Converters Control Circuits are designed to provide efficient power conversion with minimal noise generation. This is accomplished by the resonant switching of the primary side voltages, which minimizes the switching losses and the voltage/current transients that would be present in a hard switched conventional full bridge power supply.

    A Comparison Between the BiCMOS UCC3895 Phase Shift Controller and the UC3875
    This application report compares the BiCMOS UCC3895 to its bipolar predecessors, the UC3875/6/7/8 family and the UC3879 controller. All of these integrated circuits provide the control and drive signals needed to implement a full-bridge converter using phase-shifted control. The UCC3895 represents the latest offering in the Texas Instruments line of phase-shift controllers, incorporating a feature

    DN-63 The Current-Doubler Rectifier: An Alternative Rectification Technique
    The UC3875, UC3879, and UC3895 families of ICs control a bridge power stage by phase-shifting the switching of one half-bridge with respect to the other. This method allows constant-frequency pulse-width modulation in combination with resonant, zero-voltage switching for high efficiency performance. These ICs can be configured to provide control in either voltage mode or current mode operation, wi

    Synchronous Rectifiers of a Current Doubler
    Driving a current doubler synchronous rectification output stage can be a very complex task, especially for a phase shifted full bridge topology. However, using the A and B outputs of the UCC3895 along with the UCC37324 dual 4-A MOSFET driver, direct PWM control of a synchronous rectifier current doubler output stage achieves. This technique provides the proper gating and timing signals necessary
