LM2575HVSX-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575HVSX-ADJ/NOPB is a SIMPLE SWITCHER® step-down switching voltage regulator manufactured by Texas Instruments. It operates with an input voltage range of 4 V to 60 V and provides an adjustable output voltage from 1.23 V to 57 V. The device delivers a maximum output current of 1 A with a typical switching frequency of 52 kHz. It features a low quiescent current of 10 mA and supports operation in temperatures ranging from -40°C to +125°C. The component is housed in a TO-263-5 surface-mount package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Adjustable output voltage capability via external resistors
• Internal frequency compensation for stable operation
• Thermal shutdown protection for reliability

Voltage Regulators - DC DC Switching Regulators Applications

• Distributed power supply systems
• Pre-regulators for switching post-regulators
• Efficient on-card regulation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'NOPB' confirms lead-free and RoHS compliance status as per manufacturer specifications. Ensure the 'X' designation matches the required tape-and-reel packaging format rather than tube packaging. Confirm the specific revision level aligns with your bill of materials requirements before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an input voltage up to 60 V is required, distinguishing it from standard LM2575 variants limited to 40 V. Choose the ADJ version if the system requires a non-standard output voltage not available in fixed versions. Consider the TO-263-5 package for adequate thermal dissipation at full load currents without excessive heatsinking.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2575 family of SIMPLE SWITCHER regulators, designed for ease of use with minimal external components. The HVS variant specifically extends the maximum input voltage rating compared to standard versions. It serves as a core power management solution for converting higher bus voltages to lower regulated levels in compact electronic designs.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2575HVS-ADJ/NOPB is the tube-packaged equivalent of this reel-part. LM2575HVS-ADJ is the non-compliant predecessor. Verify pinout compatibility when substituting with other buck converters.
