There will be some switching losses as well, so some derat-
ing needs to be applied when calculating IC power dissipa-
tion.
INDUCTOR SUPPLIERS
Recommended suppliers of inductors for this product in-
clude, but are not limited to Sumida, Coilcraft, Panasonic,
TDK and Murata. When selecting an inductor, make certain
that the continuous current rating is high enough to avoid
saturation at peak currents. A suitable core type must be
used to minimize core (switching) losses, and wire power
losses must be considered when selecting the current rating.
SHUTDOWN PIN OPERATION
The device is turned off by pulling the shutdown pin low. If
this function is not going to be used, the pin should be tied
directly to V
IN
. If the SHDN function will be needed, a pull-up
resistor must be used to V
IN
(approximately 50k-100k
rec-
ommended). The SHDN pin must not be left unterminated.
