Introduction

The MAX8667ETEHR+T is a high-efficiency, multi-channel synchronous buck DC-DC converter for non-isolated applications. It is a synchronous converter with a fixed-frequency and peak current-mode control architecture. The MAX8667ETEHR+T supports a wide range of output power and board space flexibility by providing four independently adjustable output channels in a 120-pin TQFN package. It is optimized for applications requiring a wide voltage range and provides best-in-class high efficiency, ripple, transients and protections through its feature set.

Application Field

The MAX8667ETEHR+T voltage regulator is designed for high-output current applications. Its output power can reach up to 180W and it can supply up to four adjustable output channels. This voltage regulator is commonly used in electric vehicles (EV) applications, consumer electronics, communication, servers and many other industrial applications. The MAX8667ETEHR+T also features a wide input voltage range of 6V-20V and an output voltage range of 0.6V-14V making it an ideal choice to support a wide range of applications.

Working Principle

The MAX8667ETEHR+T voltage regulator works by converting the input voltage from a large voltage source (such as a battery) to the desired output voltage during the regulating process. It uses a synchronous DC-DC converter with peak current-mode control and a fixed frequency. During this process, the output voltage is regulated to the desired voltage level by the voltage mode feedback. The inductor transfers energy between the input and the output capacitor, while the output power is proportional to the amount of current flowing to the load.

The MAX8667ETEHR+T voltage regulator uses a number of protection features to ensure a safe operation. It provides over-voltage, over-current, over-temperature and short-circuit protection. In addition, it has an adjustable soft-start feature which allows for a smooth transition when the voltage is activated/controlled. The module also includes a 3MHz oscillator for precise timing and frequency tracking.

Conclusion

In conclusion, the MAX8667ETEHR+T voltage regulator is a high-efficiency, multi-channel synchronous buck DC-DC converter ideal for non-isolated applications. It is a cost-effective solution for EV applications and can be used in a wide range of industrial applications with its adjustable output voltage range of 0.6V-14V. The MAX8667ETEHR+T also features a wide range of protection features and adjustable soft-start features, making it a reliable solution for power management.
