LM2576HVS-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2576HVS-5.0/NOPB is a monolithic integrated circuit step-down voltage regulator from the SIMPLE SWITCHER family, manufactured by Texas Instruments. It operates with an input voltage range of 4 V to 63 V and provides a fixed 5 V output capable of driving up to 3 A loads. The device utilizes a buck topology with a typical switching frequency of 52 kHz. It is housed in a TO-263-5 surface-mount package and supports an operating temperature range from -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated high-voltage power switch enables efficient step-down conversion without external driver components.
• Fixed internal oscillator ensures stable operation at a nominal 52 kHz switching frequency.
• Built-in thermal shutdown and cycle-by-cycle current limiting provide comprehensive fault protection.

Voltage Regulators - DC DC Switching Regulators Applications

• Distributed power supply architectures requiring high input voltage tolerance
• Efficient pre-regulator stages for downstream linear regulators
• Battery-powered systems utilizing high-voltage source inputs

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'HVS' confirms the high-voltage variant (up to 63 V) and the '-5.0' indicates the fixed 5 V output. Ensure the 'NOPB' designation matches RoHS compliance requirements. Confirm the TO-263-5 package type aligns with PCB footprint specifications before ordering.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when input voltages exceed standard regulator limits but require a fixed 5 V output. The high-voltage capability simplifies designs by reducing the need for complex pre-regulation circuits. Consider thermal management strategies due to the 3 A load capacity and power dissipation characteristics inherent to buck converters.
