Quick Detail:
20-A, 18â“60-V Input Auto-Track Compatible Isolated DC/DC
Converter
Description:
The PTB78520W is a 20-A rated, wide-input (18-60 V) isolated DC/DC
converter that incorporates Auto-Track™ power-up sequencing. This
allows these modules to simultaneously power up with any other
downstream non-isolated, AutoTrack compliant module.
The PTB78520W module provides two outputs, each regulated to the
same voltage. During power up, the voltage at ‘VO Bus’ rises first,
allowing this output to provide input power to any downstream
non-isolated module. The voltage from‘VO Seq’ is then allowed to
rise simultaneously, under the control of Auto-Track, along with
the outputs from the downstream modules.
Whether used to facilitate power-up sequencing, or operated as a
stand-alone module, the PTB78520W includes many features expected
of high-performance DC/DC converter modules. The combination of
input-output isolation and a wide-input voltage range, allows
operation from either +24 V or –48 V. The wideoutput adjust enables
the output voltage to be set to to any voltage over the range,1.8 V
to 3.6 V, using a single external resistor. Precise output voltage
regulation is assured using Smart-Sense. This is a differential
remote sense that will intelligently regulate the sequenced output,
depending on its sequence status.
Other operational features include an input under-voltage lockout
(UVLO) and an output enable control. Over-current, over-voltage,
and over-temperature protection assures the module’s ability to
survive any load fault.
Typical applications include distributed power architectures in
both telecom and computing environments, particularly complex
digital systems requiring powersequencing of multiple power supply
rails.
