Dual 10-A Outputs
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.

Output currrent
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.

APPLICATIONS
•
Digital Power Systems
using UCD9XXX Digital Controllers
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.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

(1) When operating at 12V input and 500kHz, VO is limited to ≤ 2.0V.
(2) The current limit threshold is the sum of IO and the peak inductor ripple current.
(3) A 22 µF ceramic input capacitor is required for proper operation. An additional 330 µF bulk capacitor rated for a minimum of 500mA rms
of ripple current is recommended. When operating at frequencies > 500kHz the 22 µF ceramic capacitor is only recommended. Refer to
the UCD9240 controller datasheet and user interface for application specific capacitor specifications.
(4) A 47 µF ceramic output capacitor is required for basic operation. An additional 330 µF bulk capacitor is recommended for improved
transient response. Refer to the UCD9240 controller datasheet and user interface for application specific capacitor specifications.
(5) 5,000 µF is the calculated maximum output capacitance given a 1V/msec output voltage rise time. Additional capacitance or increasing
the output voltage rise rate may trigger the overcurrent threshold at start-up. Refer to the UCD9240 controller datasheet and user
interface for application specific capacitor specifications.
(6) This is the minimum ESR for all non-ceramic output capacitance. Refer to the UCD9240 controller datasheet and user interface for
application specific capacitor specifications.

APPLICATION INFORMATION
Determining the Safe Operating Area
3.0
The Safe Operating Area (SOA) curves for the
PTD08D210W are determined by the total power
dissipation of the module, the maximum ambient
temperature, and the minimum available airflow of the
application. Operation below the application airflow
curve is considered a thermally safe design. For a
given SOA, refer to the Power Dissipation curves for
the same input voltage and switching frequency to
determine each output's power dissipation. Add the
power dissipation of VOA and VOB to get the total power
dissipation. The total power dissipation can then be
used to determine the safe operating area for the
application.

For example, consider an application operating from a
12-V input and a 750-kHz switching frequency,
requiring 1.2 V @ 10 A and 3.3 V @ 6 A outputs. In
order to determine the safe operating area the power
dissipation for each of the outputs must first be
determined. Using the VI = 12 V, fSW = 750 kHz Power
Dissipation graph, the power dissipation for the 1.2 V
@ 10 A output is 2 W and the power dissipation for the
3.3 V @ 6 A output is 1.5 W. Adding the power
dissipation for both outputs results in a total power
dissipation of 3.5 W. The safe operating area can then
be determined using the VI = 12V, fSW = 750 kHz SOA
graph, the amount of airflow of the application and the
3.5-W total power dissipation. At 3.5 W and 400 LFM,
the application can operate up to 85°C, but when no
airflow is available the maximum ambient temperature
is limited to less than 71°C.

Figure 22 shows the UCD9220 power supply controller working with a single PTD08D210W, dual-output module
regulating two independent power supplies. The loop for each power supply is created by the respective voltage
outputs feeding into the Error ADC differential inputs, and completed by DPWM outputs feeding the
PTD08D210W module.

Figure 23 shows the UCD9220 power supply controller working with a single PTD08D210W power module. The
dual outputs of the PTD08D210W have been paralleled, allowing up to 20A of output current. When operating
the PTD08D210W in parallel configuration the dual inputs must be tied together and driven from a single output
of the digital power controller. Multiple PTD08D210W modules must not be paralleled.
