Adjustable Off-Line Inductorless Switching Regulator

The Supertex SR086 is an inductorless Switching Regulator designed to operate directly from a recti, ed AC line. The operating principle is to turn on a pass Transistor when the recti, ed AC is below the output voltage, and to turn it off when the output voltage reaches a speci, c level. A linear Regulator supplied by V provides an additional , xed OUT 3.3V output. Ef, ciencies of around 55% may be realized for loads up to 1.0W in 120VAC applications, with around 50% ef, ciencies for loads up to 800mW in 230VAC applications. A logic-level enable input allows the SR086 to be disabled useful when it is employed as a keep-alive power supply. By Supertex, Inc.
