LM2575HVR-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575HVR-ADJ is a step-down switching voltage regulator manufactured by TAEJIN Technology Co. It operates with a fixed internal oscillator frequency of 52 kHz and supports an adjustable output voltage range from 1.23 V to 37 V, maintaining a maximum tolerance of +/- 4% under line and load conditions. The device guarantees a continuous output current of 1 A and accepts a wide input voltage range. Designed for high efficiency, it requires only four external components for implementation. The component includes thermal shutdown and current limit protection features.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation carefully, as the LM2575 series is widely produced by multiple vendors including Texas Instruments and National Semiconductor. Confirm that the specific part number corresponds to TAEJIN Technology Co. documentation rather than other manufacturers' datasheets. Ensure the package type matches the required PCB footprint and verify RoHS compliance status through official supplier channels before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a simple buck converter topology is required with minimal external component count. The adjustable version allows flexibility in setting the output voltage within the specified range. Consider the 52 kHz switching frequency for inductor selection and the guaranteed 1 A output current for load requirements. Verify input voltage compatibility with the wide operating range specified in the technical data.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2575 family of switching regulators, which are designed for ease of use and high efficiency. The 'HV' suffix typically indicates high-voltage input capability, while 'R' denotes the reel packaging format. The 'ADJ' suffix specifies the adjustable output voltage variant. This family is known for requiring few external components and using readily available standard inductors.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Compatible substitutes include LM2575HVS-ADJ/NOPB from Texas Instruments and LM2575HVT-ADJ/LF03. Verify pinout compatibility and electrical specifications such as output current and input voltage range before substitution. Ensure the replacement part meets the same thermal and regulatory requirements.
