Voltage Regulators - DC DC Switching Regulators datasheet and documents for LA5744TP-FA-E

LA5744TP-FA-E

Voltage Regulators - DC DC Switching Regulators Overview

The LA5744TP-FA-E is a separately-excited step-down switching regulator manufactured by onsemi. It operates as a DC-DC converter with a fixed switching frequency of 300kHz and supports an output current of 3.1A. The device features synchronous rectification, a single output configuration, and surface mount packaging. It is designed for operation within a junction temperature range of -30°C to 125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Separately-excited step-down switching regulator topology
Fixed 300kHz switching frequency operation
Synchronous rectification design

Voltage Regulators - DC DC Switching Regulators Applications

DC-DC conversion in power supply systems
Voltage regulation for electronic circuits requiring 3.1A output
Embedded systems utilizing surface-mount components

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix FA-E against official onsemi documentation to confirm pinout and thermal characteristics. Ensure compatibility with the separately-excited control scheme required by this regulator type. Confirm that the 300kHz frequency aligns with system noise requirements. Validate the 3.1A current rating against peak load demands. Check for any specific mounting or thermal management guidelines provided in the datasheet.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a separately-excited buck regulator is required rather than self-excited topologies. The 300kHz frequency offers a balance between efficiency and component size. Consider the 3.1A output capability for moderate power applications. The wide operating temperature range suits industrial environments. Verify that the synchronous rectification meets efficiency targets compared to non-synchronous alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LA5744 series of switching regulators from onsemi. It is distinct from the LA5744TPGEVB evaluation board, which is a development tool for testing the chip's functionality. The LA5744TP-FA-E is the actual semiconductor device intended for integration into final products, providing the core voltage regulation capabilities.
