LV5068V-MPB-H

DC DC Switching Controllers Overview

The LV5068V-MPB-H is a single-output step-down DC/DC switching controller manufactured by onsemi. It operates with a fixed frequency of 2200 kHz and utilizes current-mode control topology. The device is housed in a 16-pin SSOP package (SSOP16, .25 inch pitch). It supports an input voltage range up to 40V and functions within an operating temperature range of -40 °C to 85 °C. The typical quiescent operation current is approximately 80 µA, facilitating low power consumption applications.

DC DC Switching Controllers Feature Summary

• Implements current-mode control for stable regulation in buck converter topologies
• Features high-frequency switching at 2200 kHz to minimize external component size
• Designed for low power consumption with approximately 80 µA operation current
• Supports clock synchronization capabilities

DC DC Switching Controllers Applications

• Battery-powered portable electronic devices requiring efficient step-down conversion
• Industrial systems utilizing 40V input rails
• Embedded controllers needing low standby power consumption

DC DC Switching Controllers Procurement Notes

Verify the specific suffix MPB-H corresponds to the required tape-and-reel or fan-fold packaging configuration as indicated in distributor listings. Confirm that the 16-pin SSOP footprint matches the target PCB design. Ensure compliance with RoHS directives and moisture sensitivity level 3 handling requirements during assembly.

DC DC Switching Controllers Selection Notes

Select this component when a non-synchronous buck controller is required with high switching frequency to reduce inductor size. The 40V rating suits applications with higher input voltages. Consider the 80 µA quiescent current for battery life optimization. Verify thermal performance within the -40 °C to 85 °C range for the intended environment.

DC DC Switching Controllers Part Context

This part belongs to the LV5068 family of low-power step-down switching regulator controllers from onsemi. The family includes variants such as LV5068 V-TLM-H for evaluation purposes. These controllers are designed for energy-efficient power management in compact form factors, leveraging current-mode control for transient response stability.

DC DC Switching Controllers Replacement Considerations

Direct substitutes include other LV5068 variants like LV5068 V-MPB-H if pinout compatibility is confirmed. Cross-reference with similar 40V buck controllers from onsemi ensuring identical SSOP16 packaging and 2200 kHz switching frequency specifications.
