LM2596HVS-12

Voltage Regulators - DC DC Switching Regulators Overview

The LM2596HVS-12 is a fixed-output step-down switching regulator manufactured by UMW, part of the LM2596HV series. It provides a stable 12V output with a maximum load current of 3A. The device supports an input voltage range up to 60V and operates at a fixed 150kHz switching frequency. It utilizes PWM control topology and features built-in thermal shutdown and current limit protection. The component is housed in a TO-263-5L surface-mount package and is designed for high efficiency with minimal external component requirements.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific manufacturer marking against official datasheets to confirm authenticity. Ensure the TO-263-5L package matches design footprint requirements. Check RoHS compliance status if environmental regulations apply. Confirm the fixed 12V output variant corresponds to the -12 suffix. Validate supplier documentation for lead times and lot traceability before finalizing orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a high-input voltage buck converter is required. The 60V input rating suits automotive or industrial bus voltages. The 3A current capacity supports moderate power loads. The fixed 12V output eliminates feedback resistor calculations. Consider thermal management due to power dissipation at high input-output differentials. Verify inductor saturation current exceeds peak switch current.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2596HV family, which extends the standard LM2596 input range. The HV designation indicates support for higher input voltages compared to standard versions. The -12 suffix specifies the fixed 12V output option. The HVS variant typically denotes surface-mount packaging. This series is widely used in general-purpose DC-DC conversion applications.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2596SX-12 from Texas Instruments offers equivalent functionality and pinout compatibility. Both devices provide 12V fixed output and 3A current capability. Verify thermal performance and package dimensions match the existing PCB layout. Ensure switching frequency characteristics align with existing filter components.
