MC34167D2TR4G Description

Short technical summary and product information.

The MC34167D2TR4G 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 used cost-effectively in step-up applications with minimal external components.

 

This device integrates key functions including a temperature-compensated reference, a fixed-frequency oscillator (72 kHz), a latching pulse-width modulator, an error amplifier, and a high-current output switch capable of handling up to 5.5A. Protective features such as cycle-by-cycle current limiting, undervoltage lockout, and thermal shutdown are included for reliability.

 

The MC34167D2TR4G operates from an input voltage range of 7.5V to 40V. It provides an adjustable output voltage and can achieve a nominal 5.05V output without an external resistor divider. The regulator supports a wide output duty cycle range of 0% to 95%.

 

Packaged in a surface-mount D2PAK-5 (TO-263-6) package, this component is suitable for various power management applications requiring efficient and reliable DC-DC conversion. It also features a standby mode that reduces power supply current.
