LTSpice Simulations</h2>
|
|
<ul>
|
|
<li>The LTSpice circuit includes input and output resistors for input and output power calculations</li>
|
|
<li>An RC circuit can be added at the input for time-delay for output capacitor charging</li>
|
|
<li>Output power = (16V)(2A(max))=32 Watts</li>
|
|
<li>Input power = (12V)(Max FET current). Max FET current should be 2-3x the desired output current</li>
|
|
<li>Rsense = Vsense(min)/IL(max). Vsense is given in LT1619 Datasheet: 40mV(min). For IL, we are using max FET current<ul>
|
|
<li>For Rsense, a smaller R value gives less output ripple voltage in simulation.</li>
|
|
<li>Rsense is basically setting the current through the FET</li>
|
|
</ul>
|
|
</li>
|
|
<li>Voltage divider equation can be found in datasheet for LT1619</li>
|
|
</ul>
|

Altium</h2>
|
|
<ul>
|
|
<li>Inductor is 10uH MSS1210-103MEB. Dr. Bazuin suggested its use as Sunseeker has lots of them</li>
|
|
<li>Replaced the SI9804DY FET (used in LTSpice) with the FDS6680A as the SI is obsolete</li>
|
|
<li>Replaced the MBR735 Schottky (used in LTSpice) with the MBRD835LT4G because 735 is not surface mount</li>
|
|
</ul>
