Description
The PTH05010 series of non-isolated
power modules are small in size but big on
performance and flexibility. Their high
output current, compact footprint, and
industry-leading features offers system
designers a versatile module for powering
complex multi-processor digital systems.
The series employs double-sided surface
mount construction and provides high-
performance step-down power conversion
for up to 15 A of output current from a
5-V input bus voltage. The output volt-
age of the PTH05010W can be set to any
value over the range, 0.8 V to 3.6 V, using
a single resistor.
This series includes Auto-Track™.
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, output voltage adjust (trim),
and margin up/down controls. 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 industry’s high-speed
DSPs, micro-processors and bus drivers.
