shielded inductor. The remaining components should also be
placed as close as possible to the IC. Please see Application
Note AN-1229 for further considerations and the LM2738 de-
mo board as an example of a four-layer layout.
RECOMMENED OPERATING AREA DUE TO MINIMUM
ON TIME
The LM2738 operates over a wide range of conditions, which
is limited by the ON time of the device. A graph is provided to
show the recommended operating area for the "X" at the full
load (1.5A) and at 25°C ambient. The "Y" version of the
LM2738 operates at a lower frequency and therefore oper-
ates over the entire range of operating voltages.
