• Manufacturer Part Number: NCP1729_06
• Description: Switched Capacitor Voltage Inverter
• Manufacturer: ONSEMI [ON Semiconductor]

is connected to ground. It provides a line and load regulated output of 7.6 V at up to 300 mA with a input voltage of 5.0 V. The
output will regulate at a level of V
line. The performance characteristics are shown below.
This converter is a combination of Figures 42 and the shunt regulator to close the loop. In this case the anode of the regulator
