LA5735MC-AH

Voltage Regulators - DC DC Switching Regulators Overview

The LA5735MC-AH is a monolithic switching voltage regulator manufactured by onsemi, designed for high-efficiency DC-DC conversion. It operates as a buck converter with an adjustable output voltage range from 1.23V to 32V. The device supports a maximum switch current of 700mA and functions at a fixed switching frequency of 300kHz. It accepts an input voltage between 4.5V and 32V. The component is housed in an 8-SOIC surface-mount package and is rated for operation within a junction temperature range of -30°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• On-board DC-DC conversion modules for automotive electronics

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component authenticity carefully as this part is officially discontinued. Confirm that the specific suffix matches the required specifications, noting that distributor listings may contain conflicting data regarding output adjustability versus fixed voltage variants. Ensure compliance with RoHS directives and check moisture sensitivity levels before storage and reflow soldering processes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a non-synchronous buck topology is acceptable for cost-sensitive designs. It is suitable for applications where the 700mA output current meets load requirements without needing external pass transistors. Consider the 8-SOIC package constraints for thermal management and PCB layout space compared to higher-current alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LA5735 series of switching regulators produced by onsemi. It represents a legacy PMIC solution for basic voltage regulation tasks. The product line has been phased out in favor of newer integrated power management solutions, making this component relevant primarily for maintenance or existing hardware preservation projects.
