In summary, the Torex XCL206 Micro DC/DC converter has the following advantages when compared to an LDO: it is simple to use, engineers can use this high efficiency DC/DC converter by adding only two ceramic capacitors; the low temperature elevation simplifies board layout; users can design a compact application without occupying additional board space with a separate inductor; the XCL206 provides low voltage ripple in low load current situations by smoothly transitioning from PWM to PFM operation; and the XCL206 provides a lower radiation noise profile partly due to the unique structure.
