Description

  • PMP9594, 85-265VAC input, 5V/1.5A AC/DC USB Charger with Auto-Detect based on PSR Flyback with BJT Switch. This reference design provides an isolated 5V/1.5A output from a universal 85-265VAC input with an efficiency greater than 78%. Employing the UCC28722 Primary Side Regulation (PSR) Flyback controller which helps to eliminate the Optocoupler and secondary side regulation components, this design delivers additional cost savings by employing a bipolar power switch. Additionally, the design features the TPS2511 USB Dedicated Charging Port Controller and Current Limiting Power Switch to safely charge most SmartPhones and tablets

Littelfuse Silicon Enhanced ESD Diode Array (SESD)

In 2013 the USB Implementers Forum released two new interfaces: USB 3.1 and USB Type-C. Together they offer many advantages over earlier USB interfaces, but those advantages will require careful design to actualize. Specifically, products enabling USB 3.1 Type-C must take special care to provide ESD protection on the various high speed and high power lines incorporated in these new interfaces.
