BD8301MUV-E2

Overview

The BD8301MUV-E2 is a high-efficiency switching regulator manufactured by ROHM Semiconductor, designed for versatile power conversion tasks. It supports both Boost and Buck topologies within a single device. The component operates with an input voltage range of 2.5 V to 5.5 V and delivers an output current of 1 A. The adjustable output voltage spans from 2.8 V to 5.2 V. It functions at a fixed switching frequency of 1 MHz and includes shutdown capabilities. The unit is housed in a VQFNV4040-EP-20 package and operates between -25°C and +85°C.

Feature Summary

Supports dual Buck and Boost topologies for flexible step-up or step-down conversion
Integrated synchronous rectification for high efficiency
Includes shutdown function for power management

Applications

Portable battery-powered devices requiring voltage regulation
Embedded systems needing flexible input/output voltage configurations
Industrial control modules with varying supply requirements

Procurement Notes

Verify the specific datasheet version and RoHS compliance details before integration. Confirm that the VQFNV4040-EP-20 footprint matches your PCB layout. Note the NRND status indicates this part is not recommended for new designs; evaluate long-term availability and potential obsolescence risks for production planning.

Selection Notes

Select this component when a single IC must handle both step-up and step-down operations. Ensure the input source stays within the 2.5 V to 5.5 V range. Consider the 1 MHz switching frequency for inductor size trade-offs. Verify thermal performance under maximum load conditions given the 1 A output capability.

Part Context

This part belongs to the BD8301MUV series of switching regulators. It is categorized under PMIC - Power Management ICs. The manufacturer is ROHM Semiconductor. The product type is listed as Switching Voltage Regulators. It shares the VQFNV4040-EP-20 package style with other high-current regulators in the lineup.
