UCC1895, UCC2895, UCC3895• Programmable-Output Turnon Delay implements controlofa full-bridge power stage by
• Adaptive Delay Set phase shifting the switchingof one half-bridge with
Bidirectional Oscillator Synchronization respect to the other. The device allows constant
frequency pulse-width modulationin conjunction with
• Voltage-Mode, Peak Current-Mode,or Average resonant zero-voltage switching to provide high
Current-Mode Control efficiencyat high frequencies. The partis used either
• Programmable Softstart, Softstop and Chip asa voltage-modeor current-mode controller.
Disable viaa Single Pin While the UCC3895 maintains the functionalityof the
• 0%to 100% Duty-Cycle Control UC3875/6/7/8 family and UC3879,it improveson that
• 7-MHz Error Amplifier controller family with additional features such as
enhanced control logic, adaptive delay set, and
• Operationto1 MHzshutdown capability. Because the deviceis built using
• Typical 5-mA Operating Currentat 500 kHz the BCDMOS process,it operates with dramatically
• Very Low 150-μA Current During UVLO less supply current than it’s bipolar counterparts. The
UCC3895 operates witha maximum clock frequency
APPLICATIONS of1 MHz.
