The third-generation '78 series' high-performance 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 excellent line and load regulation, the modules deliver a full load power conversion efficiency of 85 percent with a 5 V output.
Key Features of the PTN78000, PTN78060 and PTN78020: * 1.5 A, 3 A and 5 A Output Current Ratings * Wide Input Voltage Range: 7 V to 36 V (or 10 x Vout) * Wide-Range Adjustable Output: 2.5 V to 12.6 V * On/Off Inhibit Control * Short-Circuit and Over-Current Protection * Over-Temperature Shutdown * -40 degrees C to 85 degrees C Operating Range * Remote Sense (PTN78020) Availability, Packaging and Pricing
PTN78000 integrated power modules are available in volume today from TI and its authorized distributors. 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. 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. Complete documentation and TI's fourth quarter 2004 Power Management Selection Guide are available through http://power.ti.com/ .
