EFFICIENCY SWITCHING
REGULATORS
DESCRIPTION
The UTC P2172 is monolithic high power switching regulators.
It can be operated in all standard switching configurations
including boost, buck, fly-back, forward, inverting and “Cuk.”
By utilizing current-mode switching techniques, they provide
excellent AC and DC load and line regulation.
FEATURES
* Wide Input Voltage Range: 3V~60V
* Low Quiescent Current: 6mA
* Very Few External Parts Required
* Self-Protected Against Overloads
* Operates in Nearly All Switching Topologies
* Flyback-Regulated Mode Has Fully Floating Outputs
* Can Be Externally Synchronized
