Description
The PTH04040W is a high-perfor-
mance 60-A rated, non-isolated, power
module, which uses the latest multi-phase
switched-mode topology. This provides
a small, ready-to-use module, that can
power the most densely populated multi-
processor systems.
The PTH04040W operates over an
input voltage range of 2.95 to 5.5 V, and
can be set to any output voltage over the
range, 0.8 V to 3.6 V, using a single exter-
nal resistor. The combination of a wide
input voltage and wide-output adjust range
allows the PTH04040W to be used in
many of high-performance applications.
These include advanced computing plat-
forms and servers that utilize either a
3.3-V or 5-V distribution bus.
These modules incorporate a compre-
hensive list of features. They include
an on/off inhibit and margin up/down
controls. A differential remote output
voltage sense ensures tight load regulation,
and an output overcurrent and overtem-
perature shutdown protect against most
load faults. A programmable under-voltage
lockout allows the turn-on threshold to
be customized.
The PTH04040W incorporates Auto-
Track. Auto-Track is a popular feature
of the PTH family that allows the outputs
of multiple modules to track a common
voltage during power-up and power-down
transitions. This greatly simplifies the
sequencing of voltages for VLSI ICs that
operate off multiple power rails.
The double-sided surface mount con-
struction has a low profile and compact
footprint. It is available in both through-
hole and surface-mount packages.
