LM2596HVS-5.0-EV

Voltage Regulators - DC DC Switching Regulators Overview

The EVVO LM2596HVS-5.0-EV is a fixed-output buck switching regulator IC designed for high-voltage input applications. It provides a stable 5V output with a maximum load current of 3A. The device supports an input voltage range up to 60V and operates at a fixed switching frequency of 150kHz. It utilizes pulse-width modulation (PWM) control topology and is housed in a TO-263-5L surface-mount package. The component features internal frequency compensation, enabling simplified external circuit design.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates all active functions required for a step-down switching regulator within a single monolithic IC.
• Incorporates built-in frequency compensation to minimize the number of required external components.
• Features thermal shutdown protection that activates during excessive junction temperature conditions.

Voltage Regulators - DC DC Switching Regulators Applications

• High-voltage to low-voltage DC-DC conversion stages
• Pre-regulator circuits for downstream linear regulators
• Battery-powered systems requiring efficient voltage stepping

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation on the component marking against EVVO specifications. Confirm the suffix 'EV' aligns with the intended product variant documentation. Ensure the TO-263-5L package dimensions match the target PCB footprint requirements before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required from inputs exceeding standard logic levels. The 60V input rating distinguishes it from lower-voltage variants. Consider the 150kHz switching frequency for balancing filter size and efficiency. Verify thermal management capabilities are sufficient for the expected 3A continuous load application.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2596HV series of buck converters, characterized by high input voltage tolerance. The 'S' or 'HVS' designation typically indicates specific thermal or electrical enhancements over standard versions. The '-EV' suffix denotes a specific manufacturing lot or variant configuration provided by EVVO for this particular fixed-voltage implementation.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other manufacturers' LM2596HV-5.0 parts. Cross-reference pinouts and thermal pad configurations carefully. Verify that alternative sources maintain the same 60V input rating and 3A current capability to ensure functional equivalence in existing designs.
