The PTH04T220/221W is the lower input voltage (2.2V to 5.5V) version of the PTH08T220/221W (4.5V to 14V),
16-A rated, non-isolated power module. These modules represent the 2nd generation of the popular PTH series
power modules and include a reduced footprint and additional features. The PTH04T221W is optimized to be
used with all ceramic capacitors.
Operating from an input voltage range of 2.2V to 5.5V, the PTH04T220/221W requires a single resistor to set the
output voltage to any value over the range, 0.69V to 3.6V. The wide input voltage range makes the
PTH04T220/221W particularly suitable for advanced computing and server applications that utilize 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-Tracksequencing is a
popular feature that greatly simplifies the simultaneous power-up and power-down of multiple modules in a
power system.
The PTH04T220/221W 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 reducing 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.
