Paralleled Voltage Regulators with Balanced Load Sharing

View Full Size Image View Original Datasheet Paralleled Voltage Regulators with Balanced Load Sharing

Paralleling voltage regulators to provide mode load current is a common technique. Forcing the amplifiers to share the load current equally is called ballasting. Using a precision low offset voltage amplifier to sense the output current from each regulator requires just milli-ohms of resistance, typically just a pcb circuit trace. Each amplifier then adjusts the output voltage of each regulator to force the output currents to be equal.
