The PMP9496 reference design is a conducted EMI-optimized (CISPR 25 Class 5) 10 W design for efficient automotive USB charger application utilizing the LM53603 regulator IC (2.1MHz fully-integrated synchronous buck for automotive application ) and TPS2549 USB switch(TPS2549-Q1 Automotive USB Charging Port Controller with Integrated Power Switch & Cable Compensation). The design accepts wide input voltage range of 7Vin to 25Vin and provides the outputs of 5V@2.1A. It features a small size and is an inexpensive and more efficient solution customized for automotive USB charger application. The board dimension of the PMP9496 PCB is 2800mil * 4000mil. Four layer PCB was used for the design.
