MIC2179 Datasheet, PDF (12/16 Pages) Micrel Semiconductor – 1.5A Synchronous Buck Regulator

MIC2179
The feedback resistors, RC compensation network, and
BIAS pin bypass capacitor should be located close to their
respective pins. To prevent ground bounce, their ground
traces and SGND should not be in the path of switching
Micrel
currents returning to the power supply ground bus. SGND
and PGND should be tied together by a ground plane that
extends under the MIC2179.
