APPLICATION NOTEINTRODUCTION 0.0054 sq. in. or 3.51 sq. mm. This will assist the powerNew ON Semiconductor ChipFETs in the leadless dissipation path away from the device (through the copper1206A package feature the same outline as popular 1206A leadframe) and into the board and exterior chassis (ifresistors and capacitors but provide all the performance of applicable) for the single device. The addition of a furthertrue power semiconductor devices. The 1206A ChipFET copper area and/or the addition of vias to other board layershas the same footprint as the body of the TSOP–6 and can will enhance the performance still further. An example ofbe thought of as a leadless TSOP–6 for purposes of this method is implemented on the Evaluation Boardvisualizing board area, but its thermal performance bears described in the next section (Figure 4).comparison with the much large SO–8.This technical note discusses the single–channel 80 milChipFET 1206A pin–out, package outline, pad patterns,28 milevaluation board layout and thermal performance.PIN–OUT1 825 milFigure 1 shows the pin–out description and Pin 1identification for the single–channel 1206A ChipFET 2 7device. The pin–out is similar to the TSOP–63 6configuration, with two additional drain pins to enhancepower dissipation and thermal performance. The legs of the18 mil4 5device are very short, again helping to reduce the thermalpath to the external heatsink/pcb and allowing a larger dieto be fitted in the device if necessary.26 milSTYLE 1:Figure 2.
