Description
The PTH05020 series of non-isolated
power modules offers OEM designers a
combination of high performance, small
footprint, and industry leading features.
As part of a new class of power modules
these products provide designers with the
flexibility to power the most complex
multi-processor digital systems using
off-the-shelf catalog parts.
The series employs double-sided surface
mount construction and provides high-
performance step-down power conversion
for up to 22 A of output current from a
5-V input bus voltage. The output volt-
age of the PTH05020W 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鈩?
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 and over-temperature
shutdown provides load fault protection.
Target applications include complex
multi-voltage, multi-processor systems
that incorporate the industry鈥檚 high-speed
DSPs, micro-processors and bus drivers.
