The PTH08T250W device is a high-performance 50-A rated, non-isolated power module. This
module represents the 2nd generation of the popular PTH series power modules with a reduced
footprint and improved features.
Operating from an input voltage range of 4.5 V to 14 V, the device requires a single
resistor to set the output voltage to any value over the range, 0.7 V to 3.6 V. The wide input
voltage range makes the this device particularly suitable for advanced computing and server
applications that utilize a loosely regulated 8-V to 12-V intermediate distribution bus.
Additionally, the wide input voltage range increases design flexibility by supporting operation
with tightly regulated 5-V, 8-V, or 12-V intermediate bus architectures.
The module incorporates a comprehensive list of features. Output overcurrent and
over-temperature shutdown protects against most load faults. A differential remote sense ensures
tight load regulation. An adjustable under-voltage lockout allows the turn-on voltage threshold to
be customized. Auto-Track™ sequencing is a popular feature that
greatly simplifies the simultaneous power-up and power-down of multiple modules in a power system.
Additionally, the capability to current share between multiple PTH08T250W modules allows for load
currents greater than 50 A on a single rail.
The device includes TurboTrans™ and the new
patent-pending SmartSync technologies. The TurboTrans feature
optimizes the transient response of the regulator while simultaneously reducing the quantity of
external output capacitors required to meet a target voltage deviation specification. Additionally,
for a target output capacitor bank, TurboTrans technology can be used to significantly improve the
regulators transient response by reducing the peak voltage deviation. SmartSync technology allows
for switching frequency synchronization of multiple modules, thus simplifying EMI noise suppression
tasks and reducing input capacitor RMS current requirements.
RSET is required to set the output voltage higher than 0.7 V. See
the Electrical Characteristics table for more
Double-sided surface mount construction provides a low profile and compact footprint.
Package options include both through-hole and surface mount configurations that are lead (Pb)-free
and RoHS compatible.
