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.
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).
