Texas Instruments has developed three new wide-input, non-isolated modules in its PT78 plug-in power module range.
Fifty percent smaller than their predecessors, the PTN78000, PTN78060 and PTN78020 series of 1.5A, 3A and 5A devices can be used in a variety of applications that require input voltages from 7V to 36V, including industrial, test and measurement instruments, distributed power, workstations and medical equipment.
The modules are lead (Pb)-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 85percent with a 5 V output.
Double-sided, open-frame construction and a small footprint make the modules suitable for high density designs. The PTN78000 comes in a 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.
Suggested 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. SMD devices are available on tape and reel.
