Introduction

LT8471EFE#TRPBF is a efficient, heat-dissipating, low-power, fully integrated single-chip DC/DC buck switching regulator which aims to offer reliable power for medium power applications such as power tools, motor drives, and consumer products.

Application Field and Working Principle

The LT8471EFE#TRPBF is suitable for a wide range of DC/DC buck conversion applications ranging from 3.3 V to 12 V and up to 25 A of continuous current output. LT8471EFE#TRPBF is a high-performance, single-chip controller/regulator that provides high efficiency, low bandwidth noise and various protection features. The LT8471EFE#TRPBF is based on a hysteretic current mode control loop. It regulates voltage by switching the power stage on and off at a certain switching frequency. The device\'s hysteretic operation mode ensures that a constant current-sense threshold is used to keep the dynamic loop bandwidth narrow and jitter free, which in turn results in low noise. Additionally, the current-limit threshold is internally set which makes the device fully programmable and also eliminates the need for external resistors for sensing current.The device features a pulse-skipping mode, which allows it to achieve very high efficiency from light to heavy loads. As the load current increases, the pulse-skipping mode will reduce the switching frequency which turns off the power switch and reduces unnecessary power dissipation.The LT8471EFE#TRPBF also offers several protection features including input under-voltage lockout, output over-voltage protection, on/digital comparator protection and reverse current protection.The LT8471EFE#TRPBF is designed to minimize external component count, making it well suited for cost-sensitive applications. It also provides low EMI and low pick-up current for improved EMI performance.

Conclusion

The LT8471EFE#TRPBF offers a great balance between high efficiency, high stability, low noise, and small size. Its advanced features, combined with a simple control loop and a large DC/DC buck output range make it a reliable choice for a wide variety of applications. Its low external component count and small size give the LT8471EFE#TRPBF the ability to be used in space-constrained applications.
