October 26, 2005—Texas Instruments Incorporated has introduced 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, according to the company.
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).
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, says TI. Their high efficiency, 84 percent for the PTN04050C and 88 percent for the PTN04050A, make them an excellent choice in many analog circuit applications, notes the company.
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.
