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-Tracksequencing 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.
