LM2576HVDP-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2576HVDP-ADJ is a monolithic integrated circuit step-down switching regulator from TAEJIN, designed for efficient DC-DC conversion. It operates with an input voltage range up to 60V and provides an adjustable output voltage between 1.23V and 52V. The device supports a maximum output current of 3A and utilizes a fixed 52kHz internal oscillator. Packaged in TO-263-5 (D2PAK), it integrates thermal shutdown and current limit protection, requiring only four external components for basic operation.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated high-voltage power switch capable of driving 3A loads
• Fixed-frequency internal oscillator eliminates external timing components
• Built-in thermal shutdown and current limit protection for reliability
• TTL-compatible shutdown pin enables low-power standby modes

Voltage Regulators - DC DC Switching Regulators Applications

• High-efficiency step-down (buck) regulators
• Pre-regulators for linear regulators
• On-card switching regulators
• Positive-to-negative converter (buck-boost) circuits

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific manufacturer datasheet for the LM2576HVDP-ADJ to confirm electrical tolerances and package dimensions. Ensure compatibility with the intended PCB footprint for the TO-263-5 package. Cross-reference official documentation for any variations in thermal performance or operating temperature ranges compared to standard LM2576 variants.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing buck converters requiring input voltages up to 60V and output currents near 3A. The adjustable output version allows flexibility for custom voltage requirements within the 1.23V to 52V range. Consider the TO-263-5 package for applications needing better thermal dissipation than smaller surface-mount options while maintaining a compact form factor.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2576 series of simple-to-use step-down switching regulators. The HV variant typically supports higher input voltages than standard versions. The DP suffix indicates the D2PAK (TO-263) surface-mount package. The ADJ designation confirms the output voltage is programmable via external resistors rather than being fixed at a standard value.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Compatible substitutes include LM2576HVS-ADJ and LM2576HV-ADJ from other manufacturers, provided they share the same pinout and electrical specifications. Verify that replacement parts support the required 60V input and 3A output capabilities.
