The XR5026 is a current mode monolithic buck switching regulator. Operating with an input range of 4.7V~40V, the XR5026 delivers 1A of continuous output current with two integrated N-Channel MOSFETs. The internal synchronous power switches provide high efficiency without the use of an external Schottky diode. At light loads, the regulator operates in continual conduction mode to maintain low output ripple. Current mode control provides tight load transient response and cycle-by-cycle current limit. The XR5026 guarantees robustness with short-circuit protection, thermal protection, current run-away protection, and input under voltage lockout. The XR5026 is available in 6-pin SOT23-6 package, which provides a compact solution with minimal external components.
