BD9150MUV-E2

Overview

The BD9150MUV-E2 is a high-efficiency dual-output step-down switching regulator manufactured by ROHM Semiconductor. It operates within an input voltage range of 4.75 V to 5.5 V, delivering up to 1.5 A per channel. The device supports adjustable output voltages from 800 mV to 2.5 V and features a fixed switching frequency of 1.5 MHz. Designed for surface-mount installation, it utilizes the VQFNV4040-EP-20 package. The component functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Dual independent output channels providing flexible power distribution
• Integrated synchronous rectification for enhanced conversion efficiency
• Compact exposed pad package design optimized for thermal dissipation

Applications

• Portable electronic devices requiring multi-rail power supplies
• Embedded systems with limited board space constraints
• Battery-powered equipment utilizing single-cell lithium-ion sources

Procurement Notes

This component carries the NRND status, indicating it is not recommended for new designs. Procurement should prioritize alternative solutions or verify long-term availability before integration into production cycles. Existing inventory may be subject to discontinuation notices. Verify current stock levels and lead times with authorized distributors prior to ordering. Designers are advised to review the manufacturer's obsolescence timeline carefully.

Selection Notes

Select this part only if the specific 4.75 V to 5.5 V input window aligns with the system architecture. The dual-output capability suits applications needing two distinct regulated rails from a single controller. Ensure the required load current does not exceed 1.5 A per channel. Consider the VQFNV4040-EP-20 footprint compatibility during PCB layout. Evaluate thermal performance requirements given the compact package size.

Part Context

The BD9150MUV-E2 belongs to ROHM’s series of efficient DC/DC converters aimed at portable electronics. It integrates power switches and control logic into a small form factor. The device simplifies power management by combining two buck converters in one package. This approach reduces component count and assembly complexity compared to discrete solutions.

Replacement Considerations

BD9152MUV-E2 offers similar dual-output functionality but accepts a wider 4.5 V to 5.5 V input range.
