Description
The PTH05060W non-isolated power
module is small in size but big on per-
formance and flexibility. Its high output
current, compact footprint, and industry-
leading features offers system designers
a versatile module for powering complex
multi-processor digital systems.
This product employs double-sided
surface mount construction and provides
high-performance step-down power
conversion for up to 10 A of output cur-
rent from a 5-V input bus voltage. The
output voltage is adjustable and can be set
to any value over the range, 0.8 V to 3.6 V,
using a single resistor.
This series includes Auto-Trackâ¢
Sequencing. Auto-Track simplifies the
task of supply voltage sequencing in a
power system by enabling modules to
track each other, or any external voltage,
during power up and power down.
Other operating features include an
on/off inhibit, margin up/down controls,
and the ability to start up into an existing
output voltage or prebias. To ensure tight
load regulation, an output voltage sense
is also provided. A non-latching over-
current trip serves as load fault protection.
Target applications include complex
multi-voltage, multi-processor systems
that incorporate the industryâs high-speed
DSPs, micro-processors and bus drivers.
