Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2576D2T-012G

LM2576D2T-012G

Voltage Regulators - DC DC Switching Regulators Overview

The LM2576D2T-012G is a monolithic integrated circuit switching regulator from the LM2576 series, manufactured by onsemi. It is designed for step-down (buck) converter applications with a fixed 12V output and a maximum load current of 3A. The device operates within an input voltage range of 4V to 40V and features a fixed internal oscillator frequency of 52kHz. It utilizes pulse width modulation control mode and includes built-in thermal shutdown and current limiting protection. The component is housed in a surface-mount TO-263 package and supports an operating junction temperature range from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix '012G' against official manufacturer documentation to confirm the fixed 12V output configuration. Ensure the ordering part number matches the required TO-263 surface mount package type. Confirm RoHS compliance status through the latest datasheet before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for designs requiring a simple buck topology with moderate efficiency needs. The 52kHz switching frequency necessitates larger passive components compared to modern high-frequency alternatives. Evaluate PCB space constraints regarding the required inductor size and verify that the 3A current rating meets the application's peak load demands.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2576 family of switching regulators, which are established solutions for basic DC-DC conversion tasks. The D2T suffix indicates the TO-263 surface mount package variant. While widely used historically, newer designs may consider higher-frequency alternatives for improved power density.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Compatible replacements include other manufacturers' LM2576 variants such as those from Texas Instruments or National Semiconductor, provided they maintain identical pinouts and electrical specifications.
