Overview
The MC34063ACN is a monolithic control circuit produced by STMicroelectronics, designed for DC-DC voltage conversion. This device integrates an internal temperature-compensated reference, a comparator, a duty cycle controlled oscillator with an active current limit circuit, a driver, and a high current output switch. It is capable of operating in step-down, step-up, and voltage-inverting configurations, requiring a minimum number of external components. The output voltage can be adjusted using two external resistors with a 2% reference accuracy.
