Compatible 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) C 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.

The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. A. RSET is required to set the output voltage higher than 0.7 V. See the Electrical Characteristics table.
