The onsemi MC33166T is a versatile buck-boost switching regulator IC designed for adjustable positive or negative output voltage configurations. This component, packaged in a TO-220-5 through-hole configuration, supports input voltages ranging from 7.5V to 40V and can deliver an output current of up to 3.3A from its internal switch. Featuring a switching frequency of 72kHz, the MC33166T offers a flexible output voltage adjustable from a minimum of 5.05V up to 40V (switch), making it suitable for applications requiring both step-up and step-down voltage conversion. Its non-synchronous rectifier topology and operation across an ambient temperature range of -40°C to 85°C make it a robust solution for automotive, industrial, and power supply applications.
