TPS43000 Synchronous Boost
PMP2631: From a Li-Ion battery the PMP2631 supplies 5V @ 3A with the best possible efficiency due to the sync-boost topology.
Negative Synchronous Buck -2.2V@6A
PMP5165: This “upside-down” synchronous buck regulates a -2.2V output @ 6A from a -5.2 input voltage and achieves a full load efficiency of 93%. Level shifting in the feedback is necessary to maintain regulation.
Flyback (-3.3V@10mA) for Seismic
PMP5317.2: This reference design provides isolated 7V, +3.3V, and -3.3V outputs at 100mW total power from a 2.6Vdc to 5.1Vdc input. With total power loss below 40mW, the full load efficiency is over 70%. The minimum load losses are kept below 25mW. The TPS43000 is used to control this multiple-output flyback converter. The entire circuit fits onto a 1 square inch, single-sided circuit board.
Flyback (7V@3.5mA) for Seismic - PMP5317.3 - TI Tool Folder
PMP5317: This reference design provides isolated 7V, +3.3V, and -3.3V outputs at 100mW total power from a 2.6Vdc to 5.1Vdc input. With total power loss below 40mW, the full load efficiency is over 70%. The minimum load losses are kept below 25mW. The TPS43000 is used to control this multiple-output flyback converter. The entire circuit fits onto a 1 square inch, single-sided circuit board.
