PMP20516 — This is a synchronous buck reference design that uses TPS40322 in a dual phase topology. It is meant for 12V nominal input voltage and outputs 5V and is capable of providing up to 45A combined on both phases with excellent current sharing. The full load efficiency is 96.7% which provides great (...)
9 - 15V Input, 3.3V@25A and 5V@25A using the TPS40322
PMP6857 — The PMP6857 reference design uses the TPS40322 to generate 5V and 3.3V outputs. The supplies are capable of 25A output each. The design also takes advantage of high performance compact MOSFETs (CSD87353) to achieve efficiency over 95% for most of the load range.
