DescriptionThe PTH08T250WAZT device is a high-performance 50-A rated, non-isolated power module. Thismodule represents the 2nd generation of the popular PTH series power modules with a reducedfootprint and improved features.
Operating from an input voltage range of 4.5 V to 14V, the device requires a singleresistor to set the output voltage to any value over the range of 0.7 V to 3.6 V. The wide inputvoltage range makes the this device particularly suitable for advanced computing and serverapplications that utilize a loosely regulated 8-V to 12-V intermediate distribution bus.Additionally, the wide input voltage range increases design flexibility by supporting operationwith tightly regulated 5-V, 8-V, or 12-V intermediate bus architectures. The module incorporates acomprehensive list of features. Output overcurrent and overtemperature shutdown protects againstmost load faults. A differential remote sense ensures tight load regulation. An adjustableundervoltage lockout allows the turnon voltage threshold to be customized. Auto-Track sequencing isa popular feature that greatly simplifies the simultaneous power-up and power-down of multiplemodules in a power system. Additionally, the capability to current share between multiplePTH08T250WAZT modules allows for load currents greater than 50A on a single rail.
The device includes TurboTrans and the newpatent-pending SmartSync technologies. The TurboTrans featureoptimizes the transient response of the regulator while simultaneously reducing the quantity ofexternal 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 theregulators transient response by reducing the peak voltage deviation. SmartSync technology allowsfor switching frequency synchronization of multiple modules, thus simplifying EMI noise suppressiontasks and reducing input capacitor RMS current requirements.
RSET is required to set the output voltage higher than 0.7 V. Seethe Electrical Characteristics table for moreinformation.
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)-freeand RoHS compatible.
