DESCRIPTION  
The PTH04T240F is a high-performance 10-A rated, non-isolated power module designed to meet ultra-fast  
transient requirements for 3-GHz DSP systems like Texas Instruments' TMS320TCI6488. This module is an  
addition to the 2nd generation of the popular PTH series power modules which include a reduced footprint and  
additional features.  
Operating from an input voltage range of 2.2 V to 5.5 V, the PTH04T240F requires a single resistor to set the  
output voltage to any value over the range, 0.69 V to 2.0 V. The output voltage range makes the PTH04T240F  
particularly suitable for the 3-GHz DSP's core voltage requirements.  
The module incorporates a comprehensive list of features. Output over-current 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.  
The PTH04T240F includes new patent pending technologies, TurboTrans™ and SmartSync. 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. TurboTrans allows the PTH04T240F  
to meet the tight transient voltage tolerances required by 3-GHz DSPs with minimal output capacitance.  
SmartSync allows for switching frequency synchronization of multiple modules, thus simplifying EMI noise  
suppression tasks and reducing input capacitor RMS current requirements. The module uses double-sided  
surface mount construction to provide a low profile and compact footprint. Package options include both  
through-hole and surface mount configurations that are lead (Pb) - free and RoHS compatible.
