LM2575S-15

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575S-15 is a SIMPLE SWITCHER® step-down voltage regulator from Texas Instruments, designed for high-efficiency DC-DC conversion. It operates with an input voltage range of 4V to 40V and provides a fixed 15V output at up to 1A load current. The device utilizes a 52kHz switching frequency and employs pulse-width modulation (PWM) control. Packaged in a TO-263 surface-mount format, it integrates a 150V power switch and features thermal shutdown protection. This component is part of the LM2575 series, offering a robust solution for regulated power supplies.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated 150V power switch eliminates the need for external bootstrap components
Fixed 15V output option simplifies design for specific voltage requirements
Internal frequency compensation reduces external component count
Thermal shutdown protection safeguards against overheating conditions

Voltage Regulators - DC DC Switching Regulators Applications

Distributed power supply systems
Pre-regulators for switching regulators
Efficient on-card regulation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix configuration when sourcing replacements, as standard and NOPB variants may differ in environmental compliance. Confirm package integrity upon receipt, as the TO-263 leads require proper soldering techniques. Check manufacturer documentation for any recent pinout or electrical specification updates that might affect legacy designs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 15V output is required from a variable input source between 4V and 40V. It is suitable for applications prioritizing simplicity and low external component count over adjustable output flexibility. Consider the thermal performance of the TO-263 package relative to the expected ambient temperature and load current.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2575 family of monolithic integrated circuits used for step-down switching regulators. The 'S' suffix indicates a surface-mount TO-263 package, while '-15' denotes the fixed 15V output version. It is distinct from the adjustable ADJ variant and the higher voltage HVT/HVS series.
