A8176E5R中文资料创瑞科技数据手册PDF规格书

DESCRIPTION

The A8176 is a constant frequency, SOT-25 current mode step-up converter intended for small, low power applications. The A8176 switches at 1.0MHz 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 A8176 operates from an input voltage as low as 3.0V and can generate 24V at up to 80mA from a 5V supply.

The A8176 includes current limiting, and thermal overload protection to prevent damage in the event of an output overload.

The A8176 is available in SOT-25 package.
