Description

The PMP9517 is a high density constant voltage / constant current power supply with an 85VAC-265VAC input range and 5V/10W outptut. The design features primary side regulation (PSR) of a low cost power transistor (BJT). With low component count and low cost, the design is suitable for USB type power supplies used in smart phones, tablets, PDAs or digital cameras. This design is similar to PMP9135 but with a smaller overall size.

Features
  • Primary Side Regulation (PSR)
  • +/- 5% Voltage Regulation
  • +/- 5% Current Regulation
  • Low Stand-by Power
  • High Voltage Startup
  • Low Cost BJT control
