Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2575SX-15/NOPB

LM2575SX-15/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575SX-15/NOPB is a SIMPLE SWITCHER® step-down voltage regulator from Texas Instruments, housed in a TO-263-5 (D2PAK) surface-mount package. It provides a fixed 15V output with a maximum load current of 1A. The device operates with an input voltage range of 4V to 40V and features a typical switching frequency of 52kHz. Internal compensation allows for minimal external component usage. Key protection mechanisms include thermal shutdown and cycle-by-cycle current limiting.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated buck topology with internal oscillator and frequency compensation
Fixed 15V output option within the LM2575 series
Built-in thermal shutdown and cycle-by-cycle current limit

Voltage Regulators - DC DC Switching Regulators Applications

General-purpose DC/DC power supplies
Pre-regulators for linear post-regulator circuits
Efficient battery-powered systems requiring step-down conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'SX' against the official Texas Instruments datasheet to confirm it denotes the standard TO-263-5 package variant. Ensure the part number matches the exact fixed 15V output specification. Cross-reference the manufacturer's ordering information to confirm availability and compliance status before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 15V output is required from an input voltage up to 40V. It serves as a direct replacement for older non-NOPB versions. Consider the TO-263-5 package for its thermal performance compared to smaller SMD packages. Verify that the 1A current rating meets the application's peak load requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2575 family of monolithic integrated circuits designed for simple switcher applications. The series offers fixed output voltages including 3.3V, 5V, 12V, and 15V, alongside adjustable versions. These regulators are engineered to replace traditional three-terminal linear regulators, offering improved efficiency and reduced heat dissipation requirements.
