BiCMOS Advanced Phase-Shift PWM Controller供应BiCMOS相移PWM控制器

Check for Samples: UCC1895, UCC2895, UCC3895

1FEATURES DESCRIPTION供应BiCMOS相移PWM控制器

The UCC3895 is a phase-shift PWM controller that • Programmable-Output Turnon Delay供应BiCMOS相移PWM控制器

implements control of a full-bridge power stage by

• Adaptive Delay Set phase shifting the switching of one half-bridge with

• Bidirectional Oscillator Synchronization respect to the other. The device allows constant

• Voltage-Mode, Peak Current-Mode, or Average frequency pulse-width modulation in conjunction with

Current-Mode Control resonant zero-voltage switching to provide high供应BiCMOS相移PWM控制器

efficiency at high frequencies. The part is used either

• Programmable Softstart, Softstop and Chip as a voltage-mode or current-mode controller.供应BiCMOS相移PWM控制器

Disable via a Single Pin

While the UCC3895 maintains the functionality of the • 0% to 100% Duty-Cycle Control UC3875/6/7/8 family and UC3879, it improves on that

• 7-MHz Error Amplifier controller family with additional features such as

• Operation to 1 MHz enhanced control logic, adaptive delay set, and

shutdown capability. Because the device is built using • Typical 5-mA Operating Current at 500 kHz the BCDMOS process, it operates with dramatically
