Designing for Fast Load Transients
Features of the PTH Family of Non-Isolated Wide Output Adjust Power Modules
Introduction
SLTS234B – DECEMBER 2004 – REVISED FEBRUARY 2007
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
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.
The PTH/PTV family of non-isolated, wide-output adjustable power modules 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,
nonisolated modules with the same footprint and form factor. POLA parts are also ensured to be interoperable,
thereby, providing customers with 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 5
provides a quick reference to the features by product series and input bus voltage.

For simple point-of-use applications, the PTH12050 (6A) provides operating features such as an on/off inhibit,
output voltage trim, prebias start-up and overcurrent protection. The PTH12060 (10A), and PTH12010 (12A)
include an output voltage sense, and margin up/down controls. Then the higher output current, PTH12020 (18A)
and PTH12030 (26A) products incorporate overtemperature shutdown protection.
The PTV12010 and PTV12020 are similar parts offered in a vertical, single in-line pin (SIP) profile, at slightly
lower current ratings.
All of the products referenced in Table 5 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.
