AX5523-High Efficiency 1.2MHz 2A Step Up ConverterDataSheet

GENERAL D*CRIPTIONG
The AX5523 is a constant frequency, 6-pin SOT23 current mode step-up converter intended for *all, low power applications. The AX5523 switches at 1.2MHz and allows the use of tiny, low cost capacitors and inductors 2mm or less in height. Internal soft-start results in *all inrush current and extends battery life.
The AX5523 features automatic shifting to pulse frequency modulation mode at light loads. The AX5523 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The AX5523 is available in a *all 6-pin SOT-23 package.
