Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2576HVSX-12

LM2576HVSX-12

Voltage Regulators - DC DC Switching Regulators Overview

The LM2576HVSX-12/NOPB is a SIMPLE SWITCHER step-down voltage regulator from Texas Instruments, designed for high-voltage input applications. It operates with an input voltage range of 4 V to 63 V and provides a fixed 12 V output at up to 3 A. The device utilizes a buck topology with a switching frequency of 52 kHz. It is housed in a TO-263-5 surface-mount package and supports operation within a junction temperature range of -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated monolithic controller for simplified design
Fixed internal feedback network for 12 V output
Built-in thermal shutdown protection
Standard pinout compatible with legacy designs

Voltage Regulators - DC DC Switching Regulators Applications

Distributed power architectures
High-voltage battery-powered systems
Point-of-load regulation modules

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'NOPB' indicates RoHS compliance and halogen-free status. Confirm the 'S' designation corresponds to the TO-263-5 surface-mount package. Ensure the '-12' variant matches the required 12 V fixed output specification rather than adjustable or other fixed voltages.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12 V output is required from inputs up to 63 V. The TO-263-5 package offers thermal performance suitable for 3 A loads without excessive heatsinking. Consider the 52 kHz frequency for balancing component size and efficiency requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2576HV series, which extends the standard LM2576 capabilities to higher input voltages. The 'S' suffix denotes the surface-mount D2PAK/TO-263 variant, while 'X' typically indicates tape-and-reel packaging availability.
