View the Important Notice for TI Designs covering authorized use, intellectual property matters and disclaimers.
The PMP4856 reference design uses the TPS54418 DC/DC converter and features a double-sided, small form factor layout requiring only 65 square millimeters of board space. The design is optimized for a 3.3 V input and 1.8 V output, and contains all necessary external components, including a 47µF ceramic output capacitor, a 4.7µF ceramic input capacitor, and a 1µH IHLP-1616 inductor. The TPS54418 is a 2.95 to 6 V, 4 A synchronous buck DC/DC converter with integrated 30 milliohm MOSFETS in a small 3mm x 3mm 16 pin QFN package
