Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2575MX-15/NOPB

LM2575MX-15/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575MX-15/NOPB is a SIMPLE SWITCHER® step-down voltage regulator from Texas Instruments. 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 features a 52kHz switching frequency, integrated feedback reference of 1.23V, and supports Buck and Inverting topologies. It is housed in a surface-mount SOIC-8 package (SOP-8) and functions within a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated monolithic controller for simplified design
Internal fixed-frequency oscillator for consistent operation
Built-in thermal shutdown and current limit protection

Voltage Regulators - DC DC Switching Regulators Applications

Distributed power supply systems
Pre-regulator circuits for linear regulators
Efficient buck converters for battery-powered devices

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'MX' corresponds to the SOP-8 surface-mount package variant rather than the TO-220 through-hole version. Confirm the '-NOPB' designation indicates lead-free and RoHS compliance status. Ensure the fixed 15V output rating matches the target application requirements before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 15V output is required from a 40V maximum input source. It is suitable for applications needing 1A continuous current with minimal external components. Consider the SOIC-8 package for space-constrained PCB layouts compared to larger through-hole alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2575 series of SIMPLE SWITCHER regulators, designed for ease of use and flexibility. It serves as a drop-in replacement for older National Semiconductor versions, offering improved efficiency and reliability in standard DC-DC conversion architectures.
