JW3651 Overview
Description
The JW®3651 is a high performance buck boost converter that the output voltage can be programmable from 0.9V up to 20V through external resistor. The JW3651 implements the Buck Boost converter with a single inductor architecture that operates with input voltages above, below or equal to the output voltage.
