LM2576S-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2576S-5.0/NOPB is a Texas Instruments SIMPLE SWITCHER power converter featuring a fixed 5.0V output. It operates as a step-down (buck) regulator with an input voltage range of 4V to 40V and delivers up to 3A of output current. The device utilizes a 52kHz switching frequency and is housed in a TO-263-5 surface-mount package. It includes internal feedback for precise regulation, thermal shutdown, and current limiting protection.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated monolithic switch capable of delivering 3A load current
Fixed 5.0V output option eliminates external resistor networks
Built-in thermal shutdown and cycle-by-cycle current limit protection

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load DC/DC conversion modules
Pre-regulator stages for linear regulators
Efficient buck converters for battery-powered systems

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'NOPB' confirms lead-free and RoHS compliance status. Confirm the 'S' designation indicates the TO-263-5 surface mount package variant rather than through-hole or high-voltage versions. Ensure the specific revision matches design requirements for thermal management and footprint compatibility.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required from a 4V to 40V input source. It is suitable for designs needing 3A continuous current without external feedback resistors. Consider the TO-263-5 package for surface-mount assembly and adequate heat dissipation capabilities compared to smaller packages.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2576 family of SIMPLE SWITCHER regulators. It shares architectural similarities with the LM2576T and LM2576SX variants but differs in package type. The LM2576S specifically denotes the surface-mount D2PAK/TO-263 configuration within the standard 40V input series.
