MAX1697UEUT#TG16 Application Field and Working Principle

Introduction

The MAX1697UEUT#TG16 is a monolithic low-dropout regulator integrated circuit from Maxim Integrated. It is a high-performance DC/DC switching regulator, typically used in automotive and industrial applications to provide power conversion and voltage regulation.

Application Field

The MAX1697UEUT#TG16 is typically used in automotive and industrial applications, where power conversion and voltage regulation are needed. It is also suitable for other space-constrained applications, such as consumer electronics, wearables, and portable devices.

The MAX1697UEUT#TG16 has a wide input voltage range and can operate directly from a 12V-36V bus. It also allows for an adjustable output voltage setting between 0.8V and 5.0V. With integrated over-temperature and over-current protection, it provides safe and reliable operation. Moreover, its small footprint, low quiescent current, and standby current make it ideal for low-power applications.

Working Principle

The MAX1697UEUT#TG16 is a synchronous step-down switching regulator that uses a high-efficiency two-stage architecture. This two-stage architecture consists of a current-mode controlled PWM step-down converter, which is followed by a linear low-dropout (LDO) regulator. This type of architecture is robust and provides fast transient response, excellent line and load regulation, and low output ripple voltage.

The regulator’s current-mode PWM control is configured to operate in a synchronous rectification mode. This ensures that the converter operates in the highest efficiency possible in both light and heavy load conditions. In addition, the converter provides up to 95% average efficiency over the load range.

The PWM step-down converter provides an adjustable output voltage, while the LDO regulator provides a stable output voltage even under varying input voltages. This reduces the magnitude of output voltage spikes. The regulator also features protective features such as over-temperature, over-voltage, short-circuit, and under-voltage protection.

Conclusion

The MAX1697UEUT#TG16 is a high-efficiency and high-performance DC/DC switching regulator from Maxim Integrated, typically used in automotive and industrial applications. It features a wide input voltage range and adjustable output voltage settings between 0.8V and 5.0V. Moreover, its current-mode PWM control ensures fast transient response, excellent line and load regulation, along with low output ripple voltage. Along with the low quiescent current and standby current, it makes it an ideal power solution for low-power applications.
