Introduction: The LM2597HVM-5 is a PMIC (Power Management Integrated Circuit) - Voltage Regulators - DC DC Switching Regulators IC which is a monolithic integrated circuit that integrates essential functions in the power-management system. It is a high input voltage, adjustable or fixed output voltage regulators with very low ripple. It is equipped with external components to set the operating frequency, transmitting the output voltage, and is capable to adjust the external components in order to transient response programmable.Application field:The LM2597HVM-5 integrated circuit is typically used for DCDC (Direct current-direct current) conversion, high power point tracking, battery charging, and currentsources in pulsed-load applications. It can handle big power levels, up to 5A from a wide voltage input range from 5V-60V. This makes it highly suitable for several high power designs such as DC/DC converters, battery managers, motor control systems and solar converters.Working principle: The LM2597HVM-5 device works as a current-sourcing buck converter which produces a regulated 5Vf output from an adjustable input voltage from 5V or 60V depending on the application requirements. It can be used to step-down and maintain a fixed output voltage or, when using an external adjustment pin, the output voltage can be programmed to different levels.The device includes several features that help the circuit manage various parameters such as protection features like input under voltage and over voltage lockout, current limitation and thermal shutdown.The device will operate as a switching regulator in response to a control signal. When operated in burst mode, the device runs at fixed frequency and enters a low quiescent mode when the input voltage drops. This helps to reduce power dissipation during light load operation.Conclusion: The LM2597HVM-5 integrated circuit is a PMIC (Power management integrated circuit) - Voltage regulators - DCDC switching regulators and is capable to supply high power levels, up to 5A and a wide voltage input range from 5V-60V, making it suitable for many high power designs such as DC/DC Converters, Battery managers, Motor control systems and Solar converters. The device provides multiple features such as protection features and low quiescent mode as well as an adjustable pin to program different output voltages levels.
