4-Switch buck-boost bi-directional DC-DC converter reference design

This DC-DC power converter reference design demonstrates a novel approach for battery backup applications. During normal operation, the converter works as a battery charger with CC-CV-Topping charging algorithm compatible for lithium-ion batteries. When DC bus power is lost, the converter (...)

Junction temperature vs. PCB copper coverage area
These are estimated power dissipation and thermal results.
Care must be taken to ensure that device junction temperature
does not exeed the maximum ratings as indicated in the datasheet.

This calculator uses the PCB copper area to estimate the device junction temperature. See notes on usage and calculation method.
