Variable Outputs Single Cell Battery 80W Heater Element Power Stage Buck Boost Reference Design

PMP20410 is a synchronous 4-switch buck-boost converter which utilizes the LM5175 controller as a heater element power stage in applications such as E-Cigarettes. The output voltage can be selected from 1V to 10V at 13A to 28A using a trim resistor at the FB pin with a 0.2V to 3.1V bias voltage (...)
