BU34DV7NUX-GE2

Overview

The BU34DV7NUX-GE2 is a synchronous boost DC/DC converter manufactured by ROHM Semiconductor. It operates within an input voltage range of 1.8 V to 5.5 V and provides a fixed output voltage of 3.4 V with a maximum output current of 300 mA. The device features a switching frequency of 600 kHz and includes an integrated power FET. It is housed in a compact 10-pin VSON package (VSON010X3030) suitable for surface mount applications. The component supports a shutdown function and operates across a temperature range of -40°C to +85°C.

Feature Summary

• Integrated synchronous rectification with built-in power MOSFETs for efficient step-up conversion
• Compact 10-pin VSON package design optimized for space-constrained portable electronics
• Supports shutdown mode to minimize quiescent current consumption during standby

Applications

• Portable electronic devices requiring battery voltage boosting
• Wearable technology with limited board space
• Consumer electronics utilizing single-cell lithium-ion or lithium-polymer batteries

Procurement Notes

Verify the current lifecycle status before procurement, as this component may be subject to discontinuation. Confirm that the 10-pin VSON footprint matches your PCB layout requirements. Ensure compatibility with the specified 3.4 V fixed output voltage for your target circuit design. Check for alternative sources if standard supply channels are unavailable due to end-of-life constraints.

Selection Notes

Select this component when a fixed 3.4 V output is required from a 1.8 V to 5.5 V input source. It is suitable for designs prioritizing high efficiency through synchronous rectification at moderate currents up to 300 mA. Consider the 600 kHz switching frequency for balancing component size and electromagnetic interference. Verify thermal performance within the -40°C to +85°C operating range for your specific application environment.

Part Context

This part belongs to ROHM's series of synchronous boost converters designed for low-power portable applications. It integrates control logic and power switches into a small outline package to reduce external component count. The family focuses on improving battery life in mobile devices through efficient power management and compact form factors.

Replacement Considerations

Check for direct substitutes within the BU34DV7NUX series or other ROHM synchronous boost converters with similar pinouts and electrical characteristics. Verify that any replacement maintains the 10-pin VSON package dimensions and 3.4 V output specification.
