    产品信息

    SR086 is an inductorless switching regulator designed to operate directly from a rectified AC line. The operating principle is to turn on a pass transistor when the rectified AC is below the output voltage, and to turn it off when the output voltage reaches a specific level.A linear regulator supplied by VOUT provides an additional fixed 3.3V output. Efficiencies of around 55% may be realized for loads up to 1.0W in 120VAC applications, with around 50% efficiencies 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.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.The circuits shown in this datasheet are not guaranteed to meet surge and conducted EMI requirements. The effectiveness of these circuits may vary with a particular application. The designer should conduct tests to ascertain compliance with applicable standards and regulations.
