LM2576HVDP-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2576HVDP-5.0 is a monolithic integrated circuit step-down switching regulator manufactured by TAEJIN Technology Co., part of the LM2576 series. It is designed for easy and convenient design of buck converters, capable of driving a 3.0A load with excellent line and load regulation. The device features a wide input voltage range up to 60V and includes a fixed 5.0V output version. Key internal components include a 52kHz fixed frequency internal oscillator and TTL shutdown capability for low power standby mode. The package type is indicated as DP, likely corresponding to a specific surface-mount or through-hole configuration within the manufacturer's lineup.

• Positive to negative converters (Buck-Boost)
• Power supply for battery chargers

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact physical package dimensions and pinout for the 'DP' suffix against TAEJIN Technology's official datasheet, as this designation may differ from standard industry packages like TO-263 or TO-220. Confirm moisture sensitivity level (MSL) ratings if lead-free soldering processes are required. Ensure the supplier provides the specific TAEJIN data sheet rather than generic National Semiconductor documents to guarantee parameter accuracy.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5.0V output is required from an input voltage up to 60V. It is suitable for applications needing a guaranteed 3.0A output current with minimal external component count. Consider the thermal performance requirements given the 3.0A capacity and the specific 'DP' package thermal characteristics. Verify that the 52kHz switching frequency aligns with the inductor selection and EMI constraints of the target application.

Voltage Regulators - DC DC Switching Regulators Part Context

The LM2576 series represents a family of popular three-terminal switching regulators often used as replacements for linear regulators. The LM2576HV variant specifically supports higher input voltages compared to the standard LM2576. TAEJIN Technology manufactures these devices, offering fixed voltage options including 3.3V, 5.0V, 12V, and 15V, alongside adjustable versions. This specific model targets cost-effective, high-efficiency DC-DC conversion solutions.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Cross-reference with LM2576HV-5.0/NOPB from Texas Instruments for functional compatibility. Verify pin-to-pin compatibility and thermal resistance values between the TAEJIN DP package and alternative manufacturers' packages such as TO-263 or TO-220 before substitution.
