Device Overview

Summary

SR10 is a non-isolated, capacitor-coupled, switched shunt regulator designed to operate directly from the AC line. Output voltage can be either fixed at 6.0V, 12V, or 24V using an internal feedback divider or be adjusted over a 6.0V to 28V range using an external feedback divider. Output current capability is scalable to 50mA, by selection of the series coupling capacitor (CS) on the AC line. Standby power can be under 20mW, and efficiencies of 75% are possible depending upon configuration and degree of transient protection. All components except for CS are low voltage, easing PCB layout and alleviating high voltage creepage concerns. Inherent short circuit protection is afforded by the reactance of the CS series capacitor, which limits current even with a dead short on the output. Overcurrent protection (OCP) shuts off the shunt during a line transient. Refer to application note AN-H65 for further information.

The SR10 is an inductorless switching power supply controller intended for operation directly from a rectified 120/240VAC line. Due to the capacitor-coupled, switched shunt topology (CCSS), it exhibits low standby power and good efficiency while employing no magnetics nor high voltage electrolytic capacitors. To meet a wide variety of applications, the SR10DB1 is highly configurable. Many...
