Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2576HVSX-15

LM2576HVSX-15

Voltage Regulators - DC DC Switching Regulators Overview

The LM2576HVSX-15 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 60 V and provides a fixed 15 V output at up to 3 A. The device utilizes a buck topology with a typical switching frequency of 52 kHz. It is housed in a TO-263-6 (D2PAK) surface-mount package and supports an operating junction temperature range from -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated monolithic controller for simplified design
Fixed internal switching frequency reduces external component count
Built-in thermal shutdown and current limiting protection

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for industrial systems
High-voltage battery-to-low-voltage conversion
Distributed power supply architectures

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against official documentation, as packaging variations such as tape-and-reel or cut tape may exist. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure the source document explicitly lists this part number as active or available, noting that some distributors may mark it as obsolete.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 15 V output is required from a high-voltage source up to 60 V. The TO-263 package offers thermal performance suitable for 3 A loads without excessive heatsinking. Compare against adjustable variants if flexible output voltages are needed instead of the fixed 15 V configuration.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2576HV series of SIMPLE SWITCHER regulators. It shares architectural similarities with other members like the LM2576HVS-ADJ but differs in its fixed output voltage specification. The series is characterized by high efficiency and minimal external components compared to traditional linear regulators.
