DC/DC Converter
The PQ60120HZA50 PowerQor® Zeta half-brick converter
is a next-generation, board-mountable, isolated, fixed
switching frequency DC/DC converter. The Zeta series
offers industry leading power density for standard isolated
DC/DC converters with both a wide input range and a
tightly regulated output. Targeted for use in intermediate
bus architectures, this module supplies an isolated
step down voltage from 35-75V to 12V and provides
more available power and higher efficiency than most
competitive bus converters. This converter is available
in open-frame and baseplated versions. RoHS Compliant
(see page 13).
Operational Features

rated load current
• Delivers up to 50A of output current (600W) with optional base-plate
configuration
• Wide input voltage range: 35V – 75V, with 100V 100ms input voltage
transient capability

Package: Half-brick
APPLICATION CONSIDERATIONS
Limited Output Voltage Resolution: The internal voltage
control feedback loop has limited resolution. Therefore, the output
voltage will exhibit discrete steps as the loop responds to changes
in line, load, trim, or remote sense. For instance, on close
examination, the startup ramp has a “stair-step” shape. Likewise,
a load transient response will be composed of multiple discrete
steps. The size of each step is well determined, and is shown in
Figure C. A close-up picture of a single step is shown in Figure D.
Stepping will not occur under steady state conditions.
Current share and active trim not recommended: It is
important to note that external feedback control using the sense
or trim pins will cause sustained stepping. External current
share or active trim circuits contain a separate reference voltage.
After this external feedback has taken control, the actual output
voltage can still differ from the external reference voltage by as
much as the step size. If the external feedback loop integrates
this error voltage, it will cause a limit cycle oscillation. For this
reason, external feedback using the sense and trim pins is not
recommended.
Input System Instability: This condition can occur because
any DC/DC converter appears incrementally as a negative
resistance load. A detailed application note titled “Input System
Instability” is available on the SynQor website which provides
an understanding of why this instability arises, and shows the
preferred solution for correcting it.
