Texas Instruments Inc. (TI, Dallas, TX) announced a new power supply module based on the company's SWIFT dc/dc converters that provides up to 6A of output current and a low-input voltage in a small-profile, fully featured solution that can be soldered directly onto the system board. The SWIFT module benefits point-of-load applications such as DSPs, ASICs, FPGAs, microprocessors and microcontrollers used in communications, networking, computers and a wide variety of other applications.
The PT5400 SWIFT power modules combine the TPS54610 SWIFT regulator with all necessary external components to create a complete power supply solution with input voltages of 3.3V and 5V and output voltages ranging from 1.0V to 3.3V. Further output-voltage adjustment can be achieved by adding an external resistor. The modules are efficient, with ratings of 93 percent at 4A, and additional design flexibility and protection features include short-circuit protection, standby, output inhibit and thermal shutdown.
The PT5400 modules are packaged in TI's small-profile, Excalibur case, with a five-pin, single-inline package configuration. Surface-mount, horizontal through-hole and vertical through-hole options are also available. Measuring less than 1in x 1in, Excalibur cases meet critical 8mm height tolerances in horizontal mounting. The modules can also be reflowed with the entire motherboard assembly at temperatures up to 215 degrees C.
The PT5400 SWIFT power modules are now available in sample quantities. Lead time is from 8 to 10 weeks. Pricing per module in quantities of 1,000 is $11.82.
