8.2.4 Implementing TPS25821 in USB Car Chargers
Given its small footprint, highly integrated design and ultralow standby current, the TPS25821 is ideal for use in cigarette lighter adapter (CLA) USB car chargers capable of supporting Type-C 1.5-A and BC1.2 DCP charging from same Type-C port. This makes it suitable for fast charging phones with either µB or Type-C connector. Figure 21 shows such an implementation for a two port CLA design. The LMS3635 was chosen for its wide VIN and high efficiency to allow for the compact design needed in a CLA body.
