The ON Semiconductor MC34166T is a versatile switching regulator designed for DC-to-DC conversion applications. It features a fixed oscillator frequency of 72 kHz and can deliver an output switch current in excess of 3.0 A. This device supports both step-up and voltage-inverting configurations, offering flexibility in design.
Key electrical characteristics include an adjustable output voltage, an input voltage range from 7.5 V to 40 V, and an output duty cycle ranging from 0% to 95%. Protective features such as cycle-by-cycle current limiting, undervoltage lockout, and thermal shutdown are integrated for reliability. A low power standby mode reduces supply current to 36 µA.
The MC34166T is supplied in a 5-lead TO-220 package, suitable for through-hole mounting. It is also available in a surface-mount D2PAK package. The device operates within a temperature range of 0°C to 70°C (TA).
This regulator is designed for cost-effective implementation in various power supply designs requiring stable and efficient voltage regulation.
