DESCRIPTION
The PTH08T230/231W is the higher input voltage (4.5V to 14V) version of the PTH04T230/231W (2.2V to 5.5V),
6-A rated, non-isolated power module. This regulator represents the 2nd generation of the PTH series of power
modules which include a reduced footprint and improved features. The PTH08T231W is optimized to be used in
applications requiring all ceramic capacitors.
Operating from an input voltage range of 4.5V to 14V, the PTH08T230/231W requires a single resistor to set the
output voltage to any value over the range, 0.69V to 5.5V. The wide input voltage range makes the
PTH08T230/231W particularly suitable for advanced computing and server applications that use 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 PTH08T230/231W 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 regulator's transient response by
reducing the peak voltage deviation. SmartSync allows for switching frequency synchronization of multiple
modules, thus simplifying EMI noise suppression tasks and reduces input capacitor RMS current requirements.
Double-sided surface mount construction provides a low profile and compact footprint. Package options include
both through-hole and surface mount configurations that are lead (Pb) - free and RoHS compatible.
