High Efficiency Synchronous Buck Converter, 12V Input to 1.1V at 25A using the TPS51117
PMP2993: PMP2993 uses the TPS51117 in a synchronous buck converter to generate 1.1V at 25A from a 12V input. The design was originally used in a notebook application which had a 3 cell lithium ion battery for the input. The TPS51117 has a light load efficiency mode to keep the no load losses low in portable applications.
Sync Buck for GPU (1.8V@5A)
PMP2934.1: PMP2934 has two separate TPS51117 power supplies that can be used for a variety of applications. The two outputs are 1.1V@18A and 1.8V@5A. The TPS51117 offers light load operation with simple DCAP control scheme. This design is used for GPU power supplies.
High Efficiency Synchronous Buck Converter, 12V Input to 3.3V at 22A using the TPS51117
PMP2970: PMP2970 uses the TPS51117 in a synchronous buck converter to generate 3.3V at 22A from a 12V input. The design was originally used in a notebook application which had a 3 cell lithium ion battery for the input. The TPS51117 has a light load efficiency mode to keep the no load losses low in portable applications.
