Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2597HVM-5.0

LM2597HVM-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2597HVM-5.0/NOPB is a SIMPLE SWITCHER power converter from Texas Instruments, utilizing a buck topology to provide a fixed 5 V output with a maximum current of 500 mA. It operates within an input voltage range of 4.5 V to 60 V and features a fixed switching frequency of 150 kHz. The device is housed in an SOIC-8 surface-mount package and supports operation across a temperature range of -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated monolithic controller for simplified step-down design
Fixed internal switching frequency reduces external component count
Built-in thermal shutdown and current limiting protection

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation modules
Pre-regulators for downstream linear regulators
Battery-powered systems requiring high efficiency

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (e.g., NOPB) against the manufacturer's datasheet to confirm RoHS compliance and lead-free status. Ensure the ordering part number matches the required package variant and temperature grade. Cross-reference the manufacturer's official documentation for any recent product change notifications or pinout revisions before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range up to 60 V is required alongside a moderate 500 mA output capability. The fixed 150 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the SOIC-8 package constraints for thermal dissipation if operating near maximum load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2597HV series of SIMPLE SWITCHER regulators. It shares the core control architecture with other variants in the family but differs in output voltage configuration and package type. The 'HV' designation indicates support for higher input voltages compared to standard LM2597 devices.
