The TPS84250 is an easy-to-use integrated power solution that combines a 2.5-A DC/DC converter with an inductor and passives into a low profile, QFN package. This total power solution allows as few as five external components and eliminates the loop compensation and magnetics part selection process.
The small 9 mm × 11 mm × 2.8 mm, QFN package is easy to solder onto a printed circuit board and allows a compact point-of-load design with greater than 90% efficiency and excellent power dissipation capability. The TPS84250 offers the flexibility and the feature-set of a discrete point-of-load design and is ideal for powering a wide range of ICs and systems. Advanced packaging technology affords a robust and reliable power solution compatible with standard QFN mounting and testing techniques.

PMP8372 — 具有低雜訊 LDO 分裂軌 (±5V) 輸出電壓的 40V 雙路 1A 電源模組參考設計
The PMP8372 design is optimized for small size and uses the TPS84250 step-down power module on the top- side with the TPS84259 negative output power module on the bottom-side to implement both positive and negative output voltages from a 12V/24V source. The output voltages can be adjusted from (...)
