LM2597HVN-12/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2597HVN-12/NOPB is a step-down switching regulator from the SIMPLE SWITCHER family, manufactured by Texas Instruments. It operates with an input voltage range of 4.5 V to 60 V and provides a fixed 12 V output at up to 500 mA. The device integrates a 150 kHz oscillator for efficient power conversion. It features a shutdown pin for low standby current consumption and includes thermal shutdown protection. The component is housed in an 8-pin PDIP package.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'N' confirms the PDIP package variant rather than the SOIC or TO-263 versions within the same series. Confirm RoHS compliance status via the manufacturer datasheet as manufacturing processes may evolve. Ensure the ordering part number matches the exact voltage and package requirements for your design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12 V output is required from a high-voltage source up to 60 V. The 500 mA output current limits its use to low-power applications compared to higher-current counterparts. Consider the PDIP package for through-hole mounting needs versus surface-mount alternatives like the M or S variants.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2597HV series, designed for high-input voltage buck converter applications. It shares functional similarities with the standard LM2597 but supports extended input voltage ranges. The SIMPLE SWITCHER branding indicates simplified design implementation with minimal external components required for stable operation.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2597HVM-12/NOPB offers identical electrical performance in an SOIC-8 surface-mount package. LM2597S-12/NOPB provides the same functionality in a TO-263-5 package suitable for higher thermal dissipation scenarios.
