2.2MHz, Dual-Output Buck or Boost Converter
with Internal Power MOSFETs
Layout Procedure
1) Place the power components first, with ground ter-
minals adjacent (inductor, C IN_ , and C OUT_ ). Make
all these connections on the top layer with wide,
copper-filled areas (2oz copper recommended).
2) Group the gate-drive components (bootstrap
diodes and capacitors, and VL bypass capacitor)
together near the controller IC.
3) Make the DC-DC controller ground connections as
follows:
Ordering Information (continued)
a) Create a small-signal ground plane underneath
the IC.
b) Connect this plane to SGND and use this plane
for the ground connection for the reference
(BYPASS), enable, compensation components,
feedback dividers, and OSC resistor.
c) Connect SGND and PGND together near the
input bypass capacitors and the IC (this is the
only connection between SGND and PGND).
