General Description

EC1469 is a 800mA synchronous buck converter with integrated power MOSFETs.

The EC1469 design with a current-mode control scheme, can convert wide input voltage of 7V to 40V to the output voltage adjustable from 0.8V to 90%VIN to provide excellent output voltage regulation.

The EC1469 equipped with Power-on-reset, soft start and whole protections (under-voltage, over temperature and
current-limit) into a single package.

This device, available SOT-23-6 provides a very compact system solution of external components and PCB area.
