TI Unveils 78 Series Plug-in Power Modules

Texas Instruments Inc. (TI, Dallas, TX) announced three new wide-input, non-isolated modules that simplify power system design, which build upon its PT78 plug-in power modules. The PTN78000, PTN78060 and PTN78020 Series of 1.5 A, 3 A and 5 A devices are 50% smaller than their predecessors, and can be used in a wide variety of applications that require input voltages from 7 V to 36 V, including industrial, test and measurement instruments, distributed power, workstations, and medical equipment.

The third-generation 78 Series high-performance modules are lead-free and RoHS-compliant, and provide a precisely regulated output voltage, which is adjustable via an external resistor from 2.5 V to 12.6 V. Providing line and load regulation, the modules deliver a full-load power conversion efficiency of 85% with a 5 V output. Key features of the PTN78000, PTN78060 and PTN78020 include on/off inhibit control, short-circuit and over-current protection, over-temperature shutdown, and am operating range of -40 °C to +85 °C.

The PTN78000 integrated power modules are available in volume. Double-sided, open-frame construction and a small footprint make the modules suitable for high-density designs. The PTN78000 comes in a small, 18.9 mm x 12.5 mm x 8.5 mm module, the PTN78060 in a 25.2 mm x 15.7 mm x 9 mm module, and the PTN78020 in a 37.9 mm x 22.1 mm x 9 mm module. Pricing in quantities of 1,000 units each is $8 for the PTN78000, $11 for the PTN78060 and $15 for the PTN78020. All devices are available in through-hole or SMD pin configurations. The SMD devices are available on tape and reel.
