DescriptionThe PTH08T250W deviceisa high-performance 50-A
rated, non-isolated power module. This module generationof the popular PTH witha reduced footprint and resistor range, 0.7Vto makes the this computing loosely regulated
The module incorporatesa 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™ sequencingisa popular
feature that greatly simplifies the simultaneous
power-up and power-downof multiple modulesina
power system. Additionally, the capabilityto current
share between multiple PTH08T250W modules
allows for load currents greater than50Aona single
rail.
The device includes
TurboTrans™ and the new
patent-pending
SmartSync technologies. The
TurboTrans feature optimizes the transient response the regulator while simultaneously reducing the
quantity of external output capacitors required to
meet a target voltage deviation specification.
Additionally, fora target output capacitor bank,
TurboTrans technology can be usedto significantly
improve the regulators transient response by
reducing the peak voltage deviation. SmartSync
technology allows for switching frequency
synchronizationof multiple modules, thus simplifying
EMI noise suppression tasks and reducing input
capacitor RMS current requirements.
