Attached is the application. I'm not especially worried about heat. Circuitry down-stream uses 16W at intermittent peaks, so the FET will mostly have to cope only with a little over an amp. If Ron is what they say it is that should make 0.2W tops > Where are you buying them? > What sort of price / quantity? Will have to find out. Two sample boards have been assembled by Nautech, no idea how they came by them. I specced it and left it to them. They may have come from RS for all I know (which I suggested just for these two boards anyway). Maybe they have an IR supplier, probably do. They managed to source all the SMT PICs and specialty ICs (eg a Vinculum) without too much fuss ------=_NextPart_000_0288_01C79F35.5E0A12B0 Content-Type: image/gif; name="high-side.gif" Content-Transfer-Encoding: base64 Content-Disposition: attachment; filename="high-side.gif" R0lGODlh4wDcALMAAAAAUikphFU2LZmNagwM72pqubuzqb694e/tpP//terl1O/t8e/v+/f3///3 9////ywAAAAA4wDcAEAE/vDJSau9OOvNu/9gKI5kaZ5oqq5s675wtwCNdBhSsdRxzyoCgcIQFEoG gmNxoFAKcL4oCZGoWq/YrHbL7WoRmBlAwJBekub0h2FoY6he7IGgiFsRcOu8fh0YEkR5dxlQIACH iImKi4yJho2QkZKTjC2CVgMJCAIHBVUAXKCaSANwpVuinX5VBplYCJSxioVqhrWWXQRXAAS9vr/A nljAvaJVBX+BWWAXBohNHo63IQDTK5dZCsJaulndw1ydccwY1Y+H1h0EFes3DwUHNvE5POkV2F4K BAXfdldzB/xdIWdPzToK7Q5BOYBowYNOOuQ9PLCgQIGJGCvOy9HEHIAD/ge0fcAXxxWrPwJTDiyY zhzLKSpjytxC8GUalzbV4HSp40CAGg0MWKQg8kYDeA8MxDvQAEBEeCDdKf3ZIEBOFjivSsmqtSsJ rl5hgA1Ltqw9Z4cuml3LdtrYtnDjqjg4gc4hinfvyt3LdwNdCe2UqnVHcQLShziUgkQmdR5ICuao Wk26wGHfy2Ixa97c4S3nz5g9gx7t9SADAhsrHFX4EEAAaKRj2zONesLpCjwrWi7QcII7Ba8j+u4k FBGOBccvapSN1ek7pwFSXxXNHLOYAjXEfHxQsQA0kSJ5NwCvdqjhJt7fQRO+AU3192zdw59/tYj9 IPTz69/Pv79/MxW5/haPGJb9R4EbEwiwABAOJNXEAJYxwYSBFhBHIQnyXWgBSQIh0EkvFoXIDzx8 dLGKMq8QAsAA1oyBzn8IbriMAHi4ok+JWYCCACl5nLKFOGiNgVKKGTAwQBnRILIWdWVxmABIVhgz U45X9PNFewVyIE1ZTJLlJJRcdKNPQFjAU4WVrxCQDI3LZDBAlxMkAptWfz0Q2DsLLeVQSDk5WSWZ U2phZgKrjNLmClt2VWedbfkZpiZVLMYPiFA5akdN8y3Kl6WBdrqSf3DGFqqGX82HHGUOPsCTc7xV E2RleimQ1l3abafNa61t58xxAbA32qi/kuoDsKARK+yxGhiL7LKA/rGD2FHxQCUds8wuKmtasCKi A298SrDrA9c28W1T2+VgzgIBBLADt9TKpWm78HYW77zy0jsvo6elFp0EFUnErCwAB3wIo+oIzAsx v0xbQa1OGecbAAVeq1dSd4V0CDSdPBCAQonQ0m6/Qqn3TpYGUZBvs/ambIGyKlOYYcswxyzzzDTX bPPNOL8EBA4OINFGEDggYd+ESQE9p34z8OAOd2ppGKMBCogLIRQQHqEA0RQGuF2rk+X8H6eeeorp gQB4nMbLx4IddqBjJ5WY2WagvV+M98iEAD8HcAoRoFgUuuOhKhhMCagOy+iPOFpIOYoASOCzR4ca EHEOyyYIbrnA/izgswmb4kzi4y6RPKlLoa0AnkKiYVFekJMIfKP4LssITZIx/BzyxJUXMCBA2ZMv iZmT3kW5tvBWBM9F295G/QHqXqluD/A4enPFmMfwjWaZKP1NZOCIKDzd714QwOH15Hcx6PHJUqOk Wc6n46g+W5QvvRbinMjm9ha8yeLy65fmLEO88xd34OY+gQBkbRbpw5qwgbyvvMh/CNnUTPYBD0d9 iG8qaaBsNOUOZCDGWxlTwDz6ta3FkLAy00oPVC5ylKZxQG2YqFErhjQ809GHgzhAytIU8xC1nNA7 2jihAEW2QgmIxAMwtAIRGJdEu/HnXXJpYg0hByoDtS9eV9xL/jUY1qoAtiZis8IWAC8GwPFcjGK8 UpdsskiWGwCBExLYiWF0Y65DROwiN8hYUpiykZ4QpzGSWaMVvZYBNsbFkP8aJCEvgMi2NBJZjywL ugS0yGNFspJaxKSGECaxiIRLk9XBoR4XQ0BQbgaKptQPDqH1QYp0IkuNkVYs9wUZCQTSliRL5Qus RatFQMUpBfoWAOPxrQLQ0lzK6dUCxphLXbYAYc7szyWjSZZpUrN515RmNjeIgdsYhjUB8t42yfKX k1WAlv3ijhrHyQGCtfOZ5tyANlzITnWMwJ0lIEA8CzlHnwBFKC78jVV8Ja09Ns0AlVGOr6iViAGx yxrlRI1E/inAm4u0imJ2FEM8JOac5/BumEYsTxy11Uxk6QY73HEKPUsGGGLUkz7WJCTIFOqtqlSm EOpSDEKrkVNiWiA9N0DXMtF1tHK8dAT9ckc6F6NOHvRUKTbtKb9cCFSEWmWZD+mA3I4Kmq1yFS73 CatYi/DVspr1rGhNq1rXyta2uvWtcI2rXOXiBqgxqBVGDJpDiOCAVjSIbvvxoG4MEJSVwqgQPTtC 0I5gmTbsj0J6BBcUhiAsBEGtrw9wwBOgUTW+tmKvpYSPYNOD0MLMlSwWKWq7xkrWYxkAD7CNrWxn S9va2va2tQ1tQbx6ISlO8VKEqJo1eEsh3/7WC23Dqx+G/gsv474iatCNXheCdDsbTgAIRhKnD3bX Lt9qYx9524IILYLBvqGkdPhDweUYsbuYdmVnb4jJAeWbwCyQziR3WK9+B9cfhAJ2AmpDHBZeNwoA YONxrEBEddNrmxWptpD9q9l/JYAPZxTqSdugUhV2xERCkWQOVHRTSRkZYZ3s98SLwEUWFpyA8yWO R30DXkDsx0AMXM0I/HtgLVDM4x4n4ngCSAAdEkDgT3D4cx5GRfX8ht8NN4c1ZJmBds2CDySUbVBF JvJAeIRk2B0DGYC436e4d0YugS8c28hykXc0OytoA7kYgNoByJBj95bAzi6AHvGGJyXj0UQDRuod +84c/j8v81mJBLAdDQcR5wOwoc6+u4yTxJcLLIzJxUL2ApgB0WRNPBnPIwB15sxX3iq5GTVXON/1 qnTeTsPCxx2tJqHpl+H5IewXdVj1MRItJNwZVdBmlrQXwMSNYs8vfn5q4KiY1xVRXyMOmLaC/MAR P+ou2sn8BLaiiNHJPW1HO1NWg6XqK+1bm9sXlqb0fa1buRJfZZWHeYxhrsIp6g3vfOt+Baydbc8I 5rFp8sZIn1JywHMbXBPkBoSCr+3p/fDyI2L45FG00kS8qeS7pR7HE521Fynq4rtQKVHUPhTtDG4c Id2ulUU/spFvffJbzymEM5qArnVG9oUyacUmBtDp/uNqMDbwXgoOKEJUCsQyKo2B+Xk01oCqGHQk MsEvAhg+xZ+TRpSDGXqBRpmYqDCm6/yiRXok00XdAjjnT2hFkI/LYPg8HC+K8A4AYSNMvRTTPDZA B7qEc8QOOJftvs4PKuHyd8C3/T3Q7Ljha2h1QUoat7g1MOQnP3mzM4ffLMF8fjRvD87Px/Mt4k48 qkGRnkDMW8cEFx5zCPaQFGKFP2SqqBQZx28KJypdU32uoIAWx1x1KI8BiUcc/54FPIFxj1ZVLXOw IBZC4TC67yAxU3OUo0RtWyMr4uzn060HHEn5qQS9W3Qp/luU//K0B+X5dUL+9Gty/Tdp/3/gTxr6 /m9lxDnbt/5hbdjTeoU3qed/wSaAbGF/BIgbB1iACUhO/8N67yB7C8hSdbF7U9V/EdgDOPSA6tF3 FygFg9eB6fCBIDgNGehBO+QG3RJ7r2RRQ7UyObAYrvQTC8hBUMZMrQFwS1F6eJSD4LJOtQd+5jBx M9iAGrhDfIIgP3R9QiQycfKCGQMSDRBubiWCI1gLVFiF5oeF36OFNmGAEeiFCwiGCSiGB0iGBGiG AoiG/qeGakUw8SQUTQcPDsGBXHgCdbJPM1AgeBRrdWiHtlEbFgCHGvgAQtiGBmduz/QA+3QBDCGF X4VPGgCJ9wSIIyiJGGCJIdAL2oVVpKcbDNFY/qn3GzTQCTUAgxnTQlglQv2yHCpziIjIAuuwiC6I TJaBe0bXPe+wMMAXEk2jHNoigHRxMqdRJ7khEkHxgr7BKyY0EUCkFkfEJ/1yFJaXNRcRMkqBLiFY AQBhJ6d1HTXgQT5ohX+4EZh4Vkn1eo64Y32YeetYEGx4IQ3lUa5xgxvBEAq1HfboLbE2c+YSLXyY PnM1U0wjeoM4VT20gkkFD05RD0QULbshhe9IjRWRHcqxEcBhkK/UBtgXWVSFHg45EfiXIKeVFs/R RTRQHPW4kJM0dAsJEVuHDqsREhtTLu3RjvZAXDYZAziZky+wkzz5k3LBWmEFlERZlDHTWkaZCpRK uZRMqRkRAAAAOw== ------=_NextPart_000_0288_01C79F35.5E0A12B0 Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist ------=_NextPart_000_0288_01C79F35.5E0A12B0--
