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 of 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 overtemperature shutdown protects against most load faults. A differential remote sense ensures tight load regulation. An adjustable undervoltage lockout allows the turnon 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 information.

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.
