LTC3126 is a 2.5A, 2.4V to 42V input, synchronous step-down switching regulator with integrated dual input PowerPath control. Its power stage topology enables operation from either of two independent power sources, with seamless, internally controlled transitions between inputs to ensure a stable output voltage during hot-plug and power source disconnect events.
Dual input, 2.5A step-down DC/DC achieves 95% efficiency – [Link]
