DESCRIPTION
The PTH08T240F 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 Instrument's 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 4.5 V to 14 V, the PTH08T240F 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 PTH08T240F
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 PTH08T240F includes new patented 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 PTH08T240F 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.
