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

with an input voltage of 5.0 V. The output will regulate at a level of −V
shown below. Note that the dashed line is the open loop and the solid line is the closed loop configuration for the load regulation.
This converter is a combination of Figures 37 and 32. It provides a line and load regulated output of −2.47 V at up to 300 mA
