sip32401a, sip32402a www.vishay.com vishay siliconix s15-1246-rev. d, 01-jun-15 10 document number: 63705 for technical questions, contact: powerictechsupport@vishay.com this document is subject to change without notice. the products described herein and this document are subject to specific disclaimers, set forth at www.vishay.com/doc?91000 it then follows that, assuming an ambient temperature of 70 c, the maximum power dissipation will be limited to about 324 mw. so long as the load current is below the 2.8 a limit, the maximum continuous switch cu rrent becomes a function of two things: the package power dissipation and the r ds(on) at the ambient temperature. as an example let us calcul ate the worst case maximum load current at t a = 70 c. the worst case r ds(on) at 25 c occurs at an input voltage of 1.2 v and is equal to 76 m . the r ds(on) at 70 c can be extrapolated from this data using the following formula: r ds(on) (at 70 c) = r ds(on) (at 25 c) x (1 + t c x dt) where t c is 4250 ppm/c. continuing with the calculation we have r ds(on) (at 70 c) = 76 m x (1 + 0.00425 x (70 c - 25 c)) = 90.5 m the maximum current limi t is then determined by which in case is 1.9 a. under the stated input voltage condition, if the 1.9 a current limit is exceeded the internal die temperature will rise and eventua lly, possibly damage the device. recommended board layout for the best performance, all traces should be as short as possible to minimize the induct ance and parasitic effects. the input and output capacitors should be kept as close as possible to the input and output pins respectively. connecting the central expose d pad to gnd, using wide traces for input, output, and gnd help reducing the case to ambient thermal impedance. vishay siliconix maintains worldw ide manufacturing ca pability. products may be manufactured at one of several qualified locatio ns. reliability da ta for silicon technology and package reliability represent a composite of all qu alified locations. for related documents such as package/tape drawings, part marking, and reliability data, see www.vishay.com/ppg?63705 .
