Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2575D2T-12R4G

LM2575D2T-12R4G

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575D2T-12R4G is a monolithic integrated circuit from onsemi, functioning as a step-down (buck) switching regulator. It provides a fixed 12V output with a maximum load current of 1A. The device operates within an input voltage range of 4.75V to 40V and utilizes a 52kHz internal oscillator frequency. Designed for surface-mount applications, it is housed in a D2PAK-5 package (TO-263-6). The component supports a junction temperature range from -40°C to 125°C and includes internal frequency compensation to minimize external component requirements.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix R4G against the manufacturer's latest datasheet to confirm package type and tape/reel specifications. Confirm RoHS compliance status and REACH declarations directly with onsemi documentation prior to procurement. Check for any Product Change Notifications (PCN) regarding assembly or material updates that may affect qualification. Ensure the ordering part number matches the exact electrical parameters required for the target application.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output at 1A is required from an input voltage up to 40V. The D2PAK-5 package offers thermal performance suitable for moderate power dissipation in surface-mount layouts. Consider the 52kHz switching frequency for inductor sizing and EMI constraints. Verify that the input voltage remains above the minimum threshold of 4.75V during operation to ensure proper regulator functionality.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2575 series of simple 1A step-down switching regulators. The series is known for requiring a minimal number of external components due to built-in frequency compensation. The D2T variant indicates a specific surface-mount package configuration distinct from through-hole versions like the T series. The 12R4G designation specifies the fixed 12V output voltage and packaging format.
