DESCRIPTION

The PTD08D210W is a high-performance dual 10-A

output, non-isolated digital PowerTrain module. This

module is the power conversion section of a digital

power system which incorporates TI's UCD7242 MOSFET/driver IC. The PTD08D210W must be used

in conjunction with a digital power controller such as

the UCD9240, UCD9220 or UCD9110 family. The

PTD08D210W 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 PTD08D210W 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 PTD08D210W 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 single-sided, pin-less surface

mount construction to provide a low profile and

compact footprint. The package is lead (Pb) - free

and RoHS compatible.
