15W Automotive Start Stop Power Supply




TI’s PMP9476 is a non-synchronous buck converter plus a non-sync boost controller accepting an input voltage of 3.5V to 40V, with 5V output at up to 3A of current to the load. It features a small form factor; with PFET to replace LM3481 controller rectifier to improve efficiency and low component temperature rise; and reverse polarity protection built in.
