MC34167T Description

Short technical summary and product information.

The MC34167T from On Semiconductor is a high-performance fixed-frequency power switching regulator. It is designed for use in step-down and voltage-inverting configurations, and can also be cost-effectively used in step-up applications. This device integrates key functions for DC-DC converters, including a temperature-compensated reference, a fixed-frequency oscillator, a latching pulse-width modulator, an error amplifier, and a high-current output switch.

 

Key electrical specifications include an output switch current capability exceeding 5.0 A (with product data indicating 5.5A), a fixed switching frequency of 72 kHz, and an adjustable output voltage. The device operates from an input voltage range of 7.5 V to 40 V. Protective features such as cycle-by-cycle current limiting, undervoltage lockout, and thermal shutdown are integrated for reliability.

 

The MC34167T is available in an economical 5-lead TO-220 package, suitable for through-hole mounting. It also offers a standby mode that reduces power supply current. The component is designed to provide flexibility in power supply designs, accommodating both positive and negative output configurations.
