LV5749V-TLM-E

DC DC Switching Controllers Overview

The LV5749V-TLM-E is a DC-DC switching controller manufactured by onsemi, designed for buck converter applications. It operates within an input voltage range of 8 V to 42 V and supports a maximum output current of 5 mA. The device features a fixed switching frequency of 300 kHz and is housed in a 16-pin SSOP package. It functions as a PWM regulator controller with a power dissipation rating of 670 mW. The component is rated for operation between -40°C and +85°C, ensuring reliability in various industrial environments.

DC DC Switching Controllers Feature Summary

Integrated PWM control for efficient buck topology regulation
Wide input voltage tolerance supporting high-voltage systems
Compact surface-mount packaging for space-constrained designs

DC DC Switching Controllers Applications

Industrial power supply modules
Battery-powered equipment step-down conversion
Embedded system voltage regulation

DC DC Switching Controllers Procurement Notes

Verify the specific pinout configuration against the official datasheet before integration. Confirm that the thermal requirements align with the 670 mW dissipation limit in your enclosure design. Ensure the input voltage never exceeds the 42 V maximum rating during transient conditions. Check for moisture sensitivity handling requirements if storage conditions were not strictly controlled prior to assembly.

DC DC Switching Controllers Selection Notes

Select this component when a wide input voltage range up to 42 V is required for buck conversion. It is suitable for applications needing precise PWM control with moderate output current capabilities around 5 mA. Consider the SSOP-16 package constraints for PCB layout. Evaluate the 300 kHz switching frequency against EMI requirements and inductor size preferences for the target design.

DC DC Switching Controllers Part Context

This part belongs to onsemi's line of DC-DC switching controllers, specifically optimized for buck regulator topologies. It serves as a core control element in power management integrated circuits (PMIC). The device complements other voltage regulators by providing the necessary timing and duty cycle control signals for external power switches.
