• Built-in thermal shutdown and current limit protection for system reliability

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation in industrial control systems
• Power supply stages for embedded computing modules
• Voltage stepping in automotive electronics applications

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation on the datasheet, as UMW listings may indicate alternative sourcing or generic equivalents rather than original Texas Instruments components. Confirm the suffix 'NOPB' indicates lead-free compliance if environmental standards are required. Ensure the specific part number matches the fixed 12 V output requirement, as other variants exist within the series.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12 V output is required from a high-voltage input source up to 60 V. It is suitable for applications needing moderate current capacity of 500 mA without the complexity of adjustable regulators. Consider the 150 kHz switching frequency for balancing component size and efficiency. Verify that the thermal performance of the SOIC package meets the application's heat dissipation requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2594HV series of SIMPLE SWITCHER power converters. These regulators are designed to simplify power supply design by integrating the controller, switch, and freewheeling diode into a single IC. The series offers various fixed output voltages to reduce design time and component count in standard DC-DC conversion tasks.
