Description

The Supertex SR086 is an inductorless switching regulator designed to operate directly from a rectifi ed AC line. The operating principle of SR086 is to turn on a pass transistor when the rectifi ed AC is below the output voltage, and to turn it off when the output voltage reaches a specifi c level. A linear regulator supplied by VOUT provides an additional fi xed 3.3V output (SR086) or 5V output (SR087). Effi ciencies of around 55% may be realized for loads up to 1W in 120VAC applications, with around 50% effi ciencies for loads up to 800mW in 230VAC applications.

A logic-level enable input allows the SR086 to be disabled useful when the SR08x is employed as a keep-alive  ower supply.

WARNING! Galvanic isolation is not provided. Dangerous voltages are present when connected to the AC line. It is the responsibility of the designer employing the SR086 to ensure adequate safeguards are in place to protect the end user from electrical shock.
