LM2596S-3.3-EV

Voltage Regulators - DC DC Switching Regulators Overview

The EVVO LM2596S-3.3-EV is a monolithic integrated circuit designed as a step-down switching voltage regulator within the LM2596 series. It provides a fixed 3.3V output with a maximum load current of 3A and supports an input voltage range up to 40V. Operating at a fixed 150kHz switching frequency, it utilizes pulse-width modulation for efficient power conversion. The device features internal frequency compensation and a fixed-frequency oscillator, requiring minimal external components. It is housed in a TO-263-5 surface-mount package.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific suffix '-EV' corresponds to the intended manufacturer variant and packaging configuration. Confirm RoHS compliance status and moisture sensitivity level prior to integration. Ensure the supplier documentation explicitly lists the part number to avoid substitution errors with standard commercial versions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3V output is required from higher input voltages up to 40V. It is suitable for designs prioritizing simplicity and cost-efficiency over ultra-low quiescent current. The TO-263 package offers adequate thermal dissipation for moderate power levels without complex heatsinking solutions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2596 family of SIMPLE SWITCHER power converters. The 'S' designation indicates the TO-263 surface-mount package variant, while the '-3.3' specifies the fixed 3.3V output version. The '-EV' suffix typically denotes a specific manufacturing or quality tier associated with the EVVO brand portfolio.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct pin-compatible replacements include the TI LM2596S-3.3/NOPB and generic equivalents such as LM2596S-3.3 from other manufacturers. Verify thermal characteristics and exact electrical tolerances when substituting.
