The PTH08T230/231W is the higher input voltage (4.5 V to 14 V)
version of the PTH04T230/231W (2.2 V to 5.5 V), 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, 0.69 V to 5.5 V. 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.
