Most Common Step Down I.C For Laptop and Desktop Repair

A "step-down IC" typically refers to an Integrated Circuit (IC) designed to function as a voltage regulator that steps down a higher input voltage to a lower output voltage. This type of IC is also known as a "buck converter" or "buck regulator." It's commonly used in electronic devices to provide a stable and regulated power supply at a lower voltage level than the input voltage.
