Microchip SR087SG-G

非隔离

Overview

The SR087SG-G is an adjustable offline 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 5V output. Efficiencies of around 55% may be realized for loads up to 1W in 120VAC applications with around 50% efficiencies for loads up to 800mW in 230VAC applications. A logic-level enable input allows the SR087SG-G to be disabled - useful when it is employed as a keep-alive power supply.
