MC34166TG Description

Short technical summary and product information.

The ON Semiconductor MC34166TG is a high-performance fixed-frequency power switching regulator designed for DC-to-DC conversion applications. It can be used in step-down, voltage-inverting, and step-up configurations with minimal external components.

 

Key electrical specifications include an output switch current in excess of 3.0 A, a fixed oscillator frequency of 72 kHz, and an adjustable output. The device operates from a wide input voltage range of 7.5 V to 40 V. Protective features include cycle-by-cycle current limiting, undervoltage lockout, and thermal shutdown.

 

This regulator is available in a 5-lead TO-220 package, suitable for through-hole mounting. It offers an output duty cycle range of 0% to 95% and includes a precision 2% reference. The device also features a low power standby mode that reduces supply current.

 

Designed for reliability, the MC34166TG includes internal thermal shutdown and undervoltage lockout with hysteresis. It is suitable for various power supply designs requiring efficient voltage regulation.
