The PTH05T210W is a high-performance 30-A rated, non-isolated power module which utilizes a multi-phase,

switch-mode topology. This module represents the 2nd generation of the PTH series power modules which

includes a reduced footprint and improved features.

Operating from an input voltage range of 4.5 V to 5.5 V, the PTH05T210W requires a single resistor to set the

output voltage to any value over the range, 0.7 V to 3.6 V. 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.

A new feature included in this 2nd generation of PTH modules is TurboTrans™ technology (patent pending).

TurboTrans allows the transient response of the regulator to be optimized externally, resulting in a reduction of

output voltage deviation following a load transient and a reduction in required output capacitance. This feature

also offers enhanced stability when used with ultra-low ESR output capacitors.

The PTH05T210W incorporates a comprehensive list of standard features. They include on/off inhibit, a

differential remote output voltage sense which ensures tight load regulation, and an output overcurrent and

overtemperature shutdown to protect against load faults. A programmable undervoltage lockout allows the

turn-on voltage threshold to be customized. AutoTrack™ sequencing is a feature which simplifies the

simultaneous power-up and power-down of multiple modules in a power system by allowing the outputs to track

a common voltage.
