BD8311NUV-E2

Overview

The BD8311NUV-E2 is a standard single-channel boost switching regulator from ROHM Semiconductor, featuring an integrated MOSFET. It operates within an input voltage range of 3.5 V to 11 V and delivers a maximum output current of 2.5 A. The device generates adjustable output voltages between 4 V and 11 V with a fixed switching frequency of 1.2 MHz. Quiescent current is specified at 600 uA. It supports a shutdown function and functions reliably across an operating temperature range of -25°C to +85°C.

Feature Summary

Integrates a power FET within the controller for compact design
Provides non-synchronous boost conversion topology
Includes a dedicated shutdown pin for power management

Applications

Portable electronic devices requiring step-up power solutions
Battery-powered systems needing voltage regulation
General-purpose DC-DC conversion in consumer electronics

Procurement Notes

Verify the specific suffix E2 against the manufacturer's datasheet to confirm RoHS compliance status and material declarations. Ensure the ordering quantity aligns with the factory packaging specifications provided by ROHM Semiconductor. Cross-reference the component marking with official documentation to prevent counterfeit risks during acquisition.

Selection Notes

Select this component when a non-synchronous boost converter with an internal switch is required for inputs up to 11 V. It is suitable for applications where a 1.2 MHz frequency allows for smaller passive components. Consider the 600 uA quiescent current if standby power consumption is a critical design constraint compared to lower-power alternatives.

Part Context

This part belongs to the BD8311NUV series of switching regulators manufactured by ROHM Semiconductor. It is categorized under PMIC - Power Management ICs and specifically Switching Voltage Regulators. The device utilizes a VSON010V3030-EP-10 surface-mount package, designed for efficient thermal dissipation and space-constrained PCB layouts.
