Considering the TPS61165 *SEPIC* configuration, what are the formulas for calculating power dissipation and Vout max & min?
The input voltage is between 12.5V and 13.6V, the output current is 350mA, and the ambient temp is 40°C. What is the maximum and minimum output voltages to which we can design the circuit?
Thank you!
The TPS61165 does not have specific information about the SEPIC operation, but a similar device, the TPS61500, does. The following app note goes through the details of the design:
TPS61165 PSpice model may or may not have been optimized for SEPIC operation. My attempts to simulate the circuit showed unstable results. The use of PSpice is a good verification of a mathematical approach. If used as the solely tool for determining the circuit it becomes a lengthy trial and error effort.
