AX5523 - High Efficiency 1.2MHz 2A Step Up Converter

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.

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 small 6-pin SOT-23 package. .

AX5523 High Efficiency 1.2MHz 2A Step Up Converter  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 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 small 6-pin SOT-23 package.  FEATURES Integrated 80mΩ Power MOSFET 2.6V to 16V Input Voltage 1.
