Line regulation
Variation in input voltage for both these conditions
(0.5A and 4A output) shows the excellent line
regulation the ZXRD. Fig.6 shows that with 0.5A and
4A output currents, applying an increase in input
voltage from 5V to 10V , results in only small changes
in output regulation.

Transient Response
Transient response to changes in load is becoming an
increasingly critical feature of many converter circuits.
Many high speed processors make very large step
changes in their load requirements, at the same time
as having more stringent specifications in terms of
overshoot and undershoot. Fig.7 demonstrates the
excellent load transient performance of the ZXRD
series. A step change using an electronic load from 1A
to 3A is shown with corresponding output transient
performance.

Non-synchronous Applications
One of the key features of the ZXRD series, when
combined with the SimpleSync
technique, is the
flexibility in allowing engineers to choose either a
synchronous or non-synchronous architecture.
Making the design non-synchronous by removing
MOSFET N2 (the synchronous device), replacing the
ZHCS1000 with a high current diode (50WQ04FN)
and using a 2 terminal inductor, such as the Sumida
CDRH127-150MC, decreases cost slightly at the
expense of a few efficiency points. Fig.8 shows the
effect on the efficiency of the 5 to 3.3V 4A application
when the design is made non-synchronous.
