PTB78520W
Stand-Alone Operation
The combination of a wide-input and wide-output volt-
age range makes the PTB78520W an attractive product
as a stand-alone DC/DC converter. In these applications
the PTB78520W is not required to power up, or sequence
with, any non-isolated POL modules. The output voltage
can be adjusted to any value over the range, 1.8 V to 3.6 V,
and the Auto-Track features simply disregarded.
Figure 2-4 shows the the recommended configuration of
the PTB78520W when it is used as a stand-alone con-
verter. As a sequenced output voltage is not required, the
main output, ‘VO Bus’, is used to supply all the load cur-
rent. The ‘Track’ pin, and ‘VO Seq’ output are simply left
open circuit. The ‘(+)Sense’ pin can also be connected to
the ‘VO Bus’ output for improved load regulation.
When the PTB78520W is operated in this mode, the
output from ‘VO Bus’ rises promptly upon power up. The
converter also exhibits slightly less power dissipation and
a corresponding improvment in operating efficiency.
