Mikroe Power MUX 2 Click

Mikroe Power MUX 2 Click contains a highly configurable power mux and features the Texas Instruments TPS2120 multiplexer with an automatic switchover feature. The board prioritizes the main supply when present and quickly switches to auxiliary supply when the main supply drops. During switchover, the voltage drop is controlled to block reverse current before it happens and provide uninterrupted power to the load with minimal hold-up capacitance.
