LM2576HVDP-12

Voltage Regulators - DC DC Switching Regulators Overview

The LM2576HVDP-12 is a monolithic integrated circuit step-down switching regulator from the TAEJIN LM2576HV series. It provides a fixed positive output voltage of 12V with a guaranteed maximum output current of 3.0A. The device operates with a wide input voltage range, supporting high-voltage inputs typical of the HV variant. It utilizes a 52kHz fixed-frequency internal oscillator to minimize external component requirements. The regulator includes thermal shutdown and current limit protection for robust operation.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'DP' against official TAEJIN documentation to confirm package type and pinout compatibility. Ensure the source document explicitly lists this exact part number, as distributors may group it under the general LM2576HV family. Confirm RoHS compliance status if required by your manufacturing standards.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output is required from a higher input voltage rail. The 3.0A current rating suits moderate power applications. Consider the TO-263 or similar surface-mount package associated with the 'DP' suffix for PCB integration. Verify that the 52kHz switching frequency aligns with your inductor selection and EMI constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2576HV series of buck converters, designed for high-input voltage applications compared to standard LM2576 variants. The series is known for requiring minimal external components while delivering reliable performance. The '12' designation indicates the fixed 12V output version within the product line.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Compatible substitutes include the LM2576HVS-12 and LM2576HVR-12 from TAEJIN/HTC Korea, which share the same electrical specifications and functionality. Cross-reference with Texas Instruments LM2576HV-12 devices for equivalent performance, ensuring package pinouts match.
