Variable Outputs 2-Cell Battery 200W E-Cigarette Buck Boost Reference Design (PMP20327)

PMP20327 is a synchronous 4-switch buck-boost converter which utilizes the LM5175 controller for E-Cigarette applications. The output voltage can be selected from 1V to 10V at 20A to 45A using a trim resistor at the FB pin with a 0.2V to 3.1V bias voltage. This design also uses a non-sync boost regulator LMR62014 to provide the bias power for LM5175 during low Vin operation. The LM5175 pulse-by-pulse current limiting is inherent in the current-mode controller. The board includes enable, synchronization and power good functions. This design supports resistive heating element ranging from 0.1Ω to 0.5Ω to support various 200W operating conditions.
