描述 Description

The PTD08A015W is a high-performance 15-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 PTD08A015W must be used in conjunction with a digital power controller such as the UCD9240 or UCD9110 family. The PTD08A015W 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 PTD08A015W 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 PTD08A015W 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. The PTD08A015W is constructed using through-hole pins and is lead (Pb) - free and RoHS compatible.
