DESCRIPTION
The PTH04T230/231W is a high-performance, 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 PTH04T231W is optimized to be used in applications requiring all ceramic capacitors.

Operating from an input voltage range of 2.2 V to 5.5 V, the PTH04T230/231W requires a single resistor to set
the output voltage to any value over the range, 0.69 V to 3.6 V. The wide input voltage range makes the
PTH04T230/231W particularly suitable for advanced computing and server applications that use a 2.5-V, 3.3-V
or 5-V intermediate bus architecture.
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 PTH04T230/231W 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 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 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.
