Non Synchronous Buck Converter, 6V to 18V Input to 3.3V at 2A using the TPS54331 (PMP3819)
PMP3819 uses the TPS54331 to generate 3.3V at 2A from an input range of 6V to 18V. The TPS54331 is a fixed frequency non synchronous buck converter. The design uses all ceramic capacitors and the IC had an integrated high side FET. These choices allow the solution size to stay small. The design can be used in a number of applications with a wide input voltage including cable modems, set top boxes, automotive or industrial systems operating from a 12V input.
