PTH08T230W
SLTS265 – NOVEMBER 2005
DESCRIPTION
The PTH08T230W is a high-performance 6-A rated, non-isolated power module. This regulator represents the
nd
2
generation of the popular PTH series of power modules.
Operating from an input voltage range of 4.5 V to 14 V, the PTH08T230W requires a single resistor to set the
output voltage to any value over the range, 0.7 V to 5.5 V. The wide input voltage range makes the
PTH08T230W 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 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 PTH08T230W 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. Additionally, for a target output
capacitor bank, TurboTrans can be used to significantly improve the regulators transient response by reducing
the peak voltage deviation. SmartSync allows for switching frequency synchronization of multiple modules, thus
simplifying EMI noise suppression tasks and/or 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.
