LM2576D2T-15G

Voltage Regulators - DC DC Switching Regulators Overview

The LM2576D2T-15G is a monolithic integrated circuit switching regulator from the LM2576 series, manufactured by onsemi. It functions as a step-down (buck) converter with a fixed 15V output voltage. The device supports an input voltage range of 7V to 40V and delivers up to 3A of output current. Operating at a standard switching frequency of 52kHz, it utilizes pulse width modulation for regulation. The component is housed in a surface-mount TO-263 package with five pins and operates within a temperature range of -40°C to 125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix '15G' confirms the fixed 15V output variant rather than adjustable or other voltage options. Ensure the 'D2T' designation matches the required TO-263 surface-mount package type. Confirm RoHS compliance status if restricted substance regulations apply to the target assembly. Cross-reference the manufacturer part number against official onsemi documentation to validate authenticity and revision level before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 15V output is required from an input source between 7V and 40V. The 3A current capability suits moderate power applications without excessive heat sinking. The TO-263 package facilitates surface-mount assembly while providing thermal dissipation through the exposed pad. Consider the 52kHz frequency for balancing component size and efficiency needs in standard industrial environments.
