Designing for Very Fast Load Transients
Features of the PTH Family of Non-Isolated Wide Output Adjust Power Modules
POLA Compatibility
www.ti.com............................................................................................................................................................ SLTS213E – MAY 2003 – REVISED MARCH 2009
The transient response of the DC/DC converter has been characterized using a load transient with a di/dt of
1 A/
s. The typical voltage deviation for this load transient is given in the data sheet specification table using the
optional value of output capacitance. As the di/dt of a transient is increased, the response of a converter's
regulation circuit ultimately depends on its output capacitor decoupling network. This is an inherent limitation with
any DC/DC converter once the speed of the transient exceeds its bandwidth capability. If the target application
specifies a higher di/dt or lower voltage deviation, the requirement can only be met with additional output
capacitor decoupling. In these cases special attention must be paid to the type, value and ESR of the capacitors
selected.
If the transient performance requirements exceed that specified in the data sheet, or the total amount of load
capacitance is above 3000
F, the selection of output capacitors becomes more important.
The PTH/PTV family of non-isolated, wide-output adjust power modules from Texas Instruments are optimized
for applications that require a flexible, high performance module that is small in size. Each of these products are
POLA compatible. POLA-compatible products are produced by a number of manufacturers, and offer
customers advanced, non-isolated modules with the same footprint and form factor. POLA parts are also assured
to be interoperable, thereby providing customers with true second-source availability.
From the basic, Just Plug it In functionality of the 6-A modules, to the 30-A rated feature-rich PTHxx030, these
products were designed to be very flexible, yet simple to use. The features vary with each product. Table 4
provides a quick reference to the features by product series and input bus voltage.

For simple point-of-use applications, the PTHxx050 provides operating features such as an on/off inhibit, output
voltage trim, pre-bias startup, and over-current protection. The PTHxx060 (10 A), and PTHxx010 (15/12 A)
include an output voltage sense, and margin up/down controls. Then the higher output current, PTHxx020 and
PTHxx030 products incorporate over-temperature shutdown protection.
The PTVxx010 and PTVxx020 are similar parts offered in a vertical, single in-line pin (SIP) profile, at slightly
lower current ratings. Visit www.ti.com to view other power modules not listed in Table 4.
All of the products referenced in Table 4 include Auto-Track. This feature was specifically designed to simplify
the task of sequencing the supply voltages in a power system. This and other features are described in the
following sections.
