AX5523 General Description

The AX5523 is a constant frequency, 6-pin SOT23 current mode step-up converter intended for small, 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 small inrush current and extend.
