Supertex inc. SR10 Capacitor-Coupled,
Switched Shunt, (CCSS) Regulator
Features General Description The Supertex 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. в–єв–є Efficiencies up to 75% at 20mA
в–єв–є Less than 20mW standby power
в–єв–є Optional 6.0V, 12V or 24V fixed output
voltage, or adjustable from 6.0V to 28V
в–єв–є Output current scalable up to 50mA
в–єв–є 120VAC to 240VAC input
в–єв–є No magnetics
в–єв–є Inherent short circuit protection All components except for CS are low voltage, easing PCB layout and
alleviating high voltage creepage concerns. Applications
