SP6134HEU-L/TR Application Field and Working Principle

The SP6134HEU-L/TR is a DC-DC switching controller from TI. It belongs to the PMIC (Power Management, Integrated Circuit) family, falling under the Voltage Regulators & DC DC Switching Controllers category. It is an ideal product for any applications that require advanced power management and protection, such as those in high power applications.

Features and Benefits

The SP6134HEU-L/TR offers comprehensive power management and protection features. It has several advantages, mainly that it consumes less power and is capable of operating with low-cost components. It also supports High- and Low-side MOSFETs, which allows it to work with non-isolated DC-DC converters. Moreover, it has an over-voltage protection circuitry with an adjustable level of protection and an under-voltage lockout circuit with an adjustable threshold to ensure system stability in high-voltage power supplies.

Application Field

The SP6134HEU-L/TR is specifically designed for high power, non-isolated DC-DC conversion applications, such as industrial and automotive power supplies, and high-voltage power systems. It is also suitable for general-purpose buck regulator solutions, such as low voltage, stationary and mobile communication systems.

Working Principle

The SP6134HEU-L/TR utilizes an integrated 4th order, LC filter at its output, providing better filtering performance than other architectures. As a result, it is capable of efficiently transferring power across a wide range of load settings, from 0.2% to 100%.

The DC-DC switch mode control principle ensures a direct conversion of the input DC supply to a regulated output power without any intervening transformer. This helps to reduce cost and complexity in the power supply design.

The internal feedback circuit of the SP6134HEU-L/TR makes possible constant current and voltage operation over entire range of load changes. This ensures that the output is maintained within a narrow operating range initially set by the user.

Conclusion

The SP6134HEU-L/TR is an ideal product for high power applications needing advanced power management and protection. It belongs to PMIC (Power Management Integrated Circuit) family, and falls under the Voltage Regulators & DC DC Switching Controllers category. Its features and working principle make it perfect for industrial and automotive power supplies, high-voltage power systems, and other general-purpose buck regulator solutions.
