ZETA converter board provides a positive output voltage from an input voltage that varies above and below the output voltage. The board features internal bootstrap blocking device which prevents feeding the output signals to the other input signals. The MCP14628 features a diode emulation mode to enhance the light load system efficiency. The FCCM pin enables or disables the diode emulating mode. With the FCCM pin grounded, diode emulation mode is entered. The forced continuous conduction mode is entered when the FCCM pin is connected to VCC. The PWM input pin of the MCP14628 controls the high current LOWDR and HIGHDR drive signals. These signals have three distinct operating modes depending upon the state of the PWM input signal.
