DESCRIPTION

The PTD08A010W is a high-performance 10-A rated, non-isolated digital PowerTrain module. This module is the

power conversion section of a digital power system which incorporates TI's UCD7230 MOSFET driver IC. The

PTD08A010W must be used in conjunction with a digital power controller such as the UCD9240 or UCD9110

family. The PTD08A010W receives control signals from the digital controller and provides parametric and status

information back to the digital controller. Together, PowerTrain modules and a digital power controller form a

sophisticated, robust, and easily configured power management solution.

Operating from an input voltage range of 4.75 V to 14 V, the PTD08A010W provides step-down power

conversion to a wide range of output voltages from, 0.7 V to 3.6 V. The wide input voltage range makes the

PTD08A010W particularly suitable for advanced computing and server applications that utilize a loosely

regulated 8-V, 9.6-V or 12-V intermediate distribution bus. Additionally, the wide input voltage range increases

design flexibility by supporting operation with tightly regulated 5-V or 12-V intermediate bus architectures.

The module incorporates output over-current and temperature monitoring which protects against most load faults.

Output current and module temperature signals are provided for the digital controller to permit user defined

over-current and over-temperature warning and fault scerarios.

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.
