Variable Outputs Single Cell Battery 80W E-Cigarette Buck Boost Reference Design

Description

PMP20410 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 13A to 28A 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 which enables 2.7V input 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 provide 80W power.

  • 2.7V to 4.3V in, output 1V to 10V @ 13A to 28A
  • LM5175 buck-boost controller to achieve over 90% efficiency over entire operating conditions
  • Compact size, slim form factor, suitable for e-cigarette
  • Solution size: 43mm x 30mm
  • 98% peak efficiency
