Additional Infomation About Product

SR086/SR087 Adjustable Offline Inductorless Switching Regulators Features General Description Efficient Operation without Magnetics The SR086/SR087 are inductorless switching regulators designed to operate directly from a rectified No High-voltage Capacitors AC line. The operating principle is to turn on a pass Adjustable Main Output Voltage (9V to 50V) transistor when the rectified AC is below the output Additional Internal Linear Regulator: voltage and to turn it off when the output voltage - 3.3V for SR086 reaches a specific level. The ICs feature an adjustable - 5V for SR087 main output voltage of 9V to 50V and an additional fixed output of 3.3V for SR086 and 5V for SR087. Up to 100 mA Combined Output Current Efficiencies of around 55% may be realized for loads Single BOM for 120 VAC/230 VAC up to 1W in 120 VAC applications and about 50% Built-in Soft Start efficiencies for loads up to 800 mW in 230 VAC Less than 200 mW Standby Power applications. A logic-level enable input allows the SR086/SR087 to Applications be disableduseful when they are employed as keep-alive power supplies.

See Table 2-1 for pin information. WARNING Galvanic isolation is not provided. Dangerous voltages are present when connected to the AC line. It is the responsibility of the designer using the SR086/SR087 to ensure that adequate security measures are in place to protect the end user from electrical shock. The circuits shown in this data sheet are not guaranteed to meet surge and conducted EMI requirements. The effectiveness of these circuits may vary with a particular application.
