LM2597HVM-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2597HVM-ADJ/NOPB is a SIMPLE SWITCHER power converter from Texas Instruments, utilizing a buck topology. It operates with an input voltage range of 4.5 V to 60 V and provides an adjustable output voltage between 1.2 V and 57 V. The device delivers a maximum output current of 500 mA at a fixed switching frequency of 150 kHz. It features a low quiescent current of 5 mA and supports operation within a temperature range of -40°C to +125°C. Packaged in an SOIC-8 surface-mount format, it includes integrated shutdown functionality for power management.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated high-voltage switch capable of handling up to 60 V input
• Fixed 150 kHz switching frequency reduces external component size
• Adjustable output voltage via single external resistor network
• Built-in thermal shutdown and current limit protection

Voltage Regulators - DC DC Switching Regulators Applications

• Distributed power supply systems
• Pre-regulators for post-switching regulators
• Battery chargers

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status as per the manufacturer's latest documentation. Ensure the SOIC-8 package dimensions match your PCB footprint requirements. Confirm that the adjustable version meets your specific voltage regulation needs compared to fixed-output variants within the same series.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an input voltage up to 60 V is required with a moderate 500 mA load. The adjustable output allows flexibility for various rail voltages. Consider the SOIC-8 package for space-constrained designs. Evaluate the 150 kHz frequency against EMI constraints and inductor size requirements for the target application.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2597HV series, designed for high-voltage step-down applications. It is distinct from the standard LM2597 which typically has a lower maximum input voltage rating. The 'M' suffix indicates the SOIC-8 package variant, while 'ADJ' specifies the adjustable output configuration. It is part of Texas Instruments' SIMPLE SWITCHER family known for minimal external component count.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2597HVM-ADJ/NOPB is the direct equivalent. LM2597HVMX-ADJ/NOPB may differ only in reel packaging. Fixed voltage versions like LM2597HVM-5.0/NOPB are functionally similar but lack adjustability.
