TI Introduces 50 Percent Smaller, Pb-Free, Boost and Buck-Boost Power Modules with Wide Output Voltage Range19 October 2005
Texas Instruments Incorporated (NYSE: TXN)
(TI) today announced two new non-isolated DC/DC power modules for
telecommunications, industrial control and measurement systems that are 50
percent smaller than the previous generation devices and are Pb-free. The
devices feature input voltages from 2.9 V to 5.5 V and adjustable wide-output
voltages of either 5 V to 15 V (boost) or -3.3 V to 15 V (buck-boost). See
http://www.ti.com/sc05217 .
The PTN04050A is a 6-W, buck-boost, positive-to-negative converter with a
wide-range input voltage of 2.9 V to 7 V and an adjustable wide-output voltage
of -3.3 V to -15 V. The PTN04050C is a 12-W boost module that features a
2.95 V to 5.5 V input voltage range and an adjustable wide-output voltage of
5 V to 15 V. Both have an operating temperature of -40 C to +85 C and include
over-temperature protection. The easy-to-use modules offer a compact design
solution and are available in surface-mount and through-hole packages.
The devices operate from either a standard 3.3 V or 5 V bus and can be
used together to create plus and minus voltage rails required by many analog
ICs such as opamps and data converters. Their high efficiency, 84 percent for
the PTN04050C and 88 percent for the PTN04050A, make them an excellent choice
in many analog circuit applications. The latter also features on/off inhibit,
under-voltage lockout and over-current protection.
The wide-range output voltage of the devices helps reduce customer
inventory since one part can be used for a variety of applications. The
PTN04050A is well-suited for industrial controls, HVAC systems, test and
measurement, medical instrumentation, marine and avionics, and AC/DC adaptors.
Target applications for the PTN04050C include telecom, industrial test and
measurement, instrumentation, distributed power and general purpose circuits.
Both are effective for embedded applications in industrial and other
challenging environments.
Available Today
The PTN04050A and PTN04050C power modules are available now from TI and
its authorized distributors. Both devices are offered in surface-mount and
through-hole packages measuring 22 mm x 12.4 mm x 8.3 mm. They are priced
from $8.00 in 1,000 piece quantities (suggested resale pricing).
