LM2596S-5.0-EV

Voltage Regulators - DC DC Switching Regulators Overview

The EVVO LM2596S-5.0-EV is a monolithic integrated circuit step-down switching regulator operating at a fixed 150 kHz frequency. It provides a fixed 5 V output with a maximum load current of 3 A and an input voltage range up to 40 V. The device utilizes a TO-263-5L package, supports surface mount installation, and operates within a junction temperature range of -40 °C to 125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates all active functions for a buck converter topology requiring only four external components
• Includes internal thermal shutdown and current limiting protection mechanisms
• Features a fixed 150 kHz internal oscillator to minimize external filter component size
• Supports TTL shutdown capability for low-power standby modes

Voltage Regulators - DC DC Switching Regulators Applications

• Efficient step-down DC-DC power supplies
• On-card switching regulators
• Positive-to-negative converter circuits

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation on the datasheet header, as EVVO may act as a distributor or secondary source rather than the original silicon designer. Confirm that the suffix 'EV' denotes the specific evaluation or packaging variant intended for your design requirements. Ensure the component meets RoHS compliance standards if required by your manufacturing process.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 5 V output is required from an input voltage between 4.5 V and 40 V. It is suitable for applications needing up to 3 A continuous load current where high efficiency is prioritized over linear regulation. Consider the TO-263-5L package constraints and thermal dissipation needs for high-current operation.
