Product Preview
Floating, Regulated Charge
Pump
The NIS6201 charge pump is designed to provide economical, low
level power to circuits above ground level potential, such as the drive
for ORing diodes. It is a very cost−effective replacement for a small,
isolated, switching power supply.
It contains an internal linear regulator, and a versatile charge pump
to allow bias voltage supplies to be transferred from a ground
referenced source to a higher potential. The design of the charge
pump allows for any isolation voltage required, as the high voltage
components are external to the pump and can be sized accordingly.
Features
• Integrated Linear Regulator and Charge Pump
• Thermal Limit Protection
• Adjustable Voltage Output
• High Voltage Isolation
Applications
• ORing Diodes
