BD9153MUV-E2

Overview

The BD9153MUV-E2 is a dual-output synchronous buck converter manufactured by ROHM Semiconductor. It operates within an input voltage range of 4.5 V to 5.5 V and delivers up to 1.5 A per channel. The adjustable output voltage spans from 800 mV to 3.3 V. Integrated features include a 1 MHz switching frequency, shutdown control, and thermal protection. The device is housed in a compact VQFNV4040-EP-24 surface-mount package and supports an operating temperature range of -40°C to +85°C.

Feature Summary

Dual independent step-down channels for simultaneous power rail generation
Integrated synchronous MOSFETs for high conversion efficiency
Built-in thermal shutdown circuitry for operational safety

Applications

Portable electronic devices requiring multiple low-voltage rails
Embedded systems with strict space constraints
Industrial control modules utilizing single-supply architectures

Procurement Notes

This component carries the NRND status, indicating it is not recommended for new designs. Verify current availability through authorized distributors as stock levels may be limited. Confirm that existing inventory meets project requirements before finalizing procurement plans due to potential supply chain discontinuation risks.

Selection Notes

Select this regulator when designing systems requiring two isolated outputs from a narrow 5V input window. Ensure the application load does not exceed the 1.5 A per-channel limit. Consider the VQFNV4040-EP-24 footprint during PCB layout. Evaluate thermal dissipation capabilities given the enclosed package size and expected ambient conditions.

Part Context

Part of the BD9153MUV series focusing on dual-output power management. Designed for applications needing efficient voltage regulation from standard 5V sources. Competes with other dual-buck regulators offering similar pin counts and electrical specifications.
