Microchip Technology SR087
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. The ICs feature an adjustable main output voltage of 9V to 50V and an additional fixed output of 3.3V for SR086 and 5V for SR087.| Part No. | SR087 |
