Description
The PMP4425 reference design provides detailed data for evaluating and verifying a USB charger, which uses a USB charge controller, a buck converter and a shunt amplifier. Additionally the design demonstrates an automotive USB charging port that offers short-to-battery protection. With the help of the shunt amplifier, the design is capable of compensating for the effects on Vdroop when a smartphone / tablet is connected to the USB charger using a cable that is roughly 2-3 meters in length. Compliance with almost all major smartphone / tablet manufacturers is supported due to programmable current limit up to 2.1 A, BC 1.2 compliant devices are supported as well as D+/D- divider modes of 2.7V/2.7V and 1.2V.
Features
- Linear cable compensation feature
- The TI devices in this design are AEC-Q100 qualified.
- Supports CDP/SDP auto switch for small industry standard footprint based devices.
- Size: 95mm(L)X30.7mm(W)x12mm(H)
- High efficiency with 91% @ 19Vin full load
Remarks:- Only BOM is available.
