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.
