SR086
Overview
The SR086/SR087 are inductorless switching regulators 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.
- Efficient Operation without Magnetics
- No High-voltage Capacitors
- Adjustable Main Output Voltage (9V to 50V)
- Additional Internal Linear Regulator: - 3.3V for SR086 - 5V for SR087
- Up to 100 mA Combined Output Current
- Single BOM for 120 VAC/230 VAC
- Built-in Soft Start
- Less than 200 mW Standby Power
