Product Overview

SR087 inductorless switching PS demo board is an inductorless switching power supply intended for operation directly from a 120/230VAC line. Two outputs 12.6V and 5.0V are provided. The operating principle is to turn on a pass transistor when the rectified AC input is below the output voltage and to turn it off when the output storage capacitor is charged up to the regulation point. Since the output capacitor charges up on the rising edge of a sine wave reasonable efficiencies can be obtained without the use of magnetics.
  • 90 to 270VAC (45Hz to 65Hz) AC input (VIN)
  • 52% (for VIN = 120VAC) typ efficiency (full load)
  • 62mW (for VIN=120VAC) typ standby power (no load)
