Texas Instruments

Small Form Factor 10W Offline Flyback Power Supply Reference Design


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.
