Overview
The BU33DV5G-GTR is a single synchronous boost DC/DC converter IC manufactured by Rohm Semiconductor. It operates with an input voltage range of 1.75V to 4.5V and provides a positive adjustable output starting from 3.23V. The device delivers a maximum output current of 10mA and features a switching frequency of 100kHz. Packaged in a compact SC-74A (SOT-753) surface-mount housing, it integrates low-on-resistance power MOSFETs for efficient energy conversion. The component functions without external supply voltage requirements and supports operation across a temperature range of -25°C to 85°C.
Feature Summary
- Integrates synchronous rectification with built-in low-on-resistance power MOSFETs for high efficiency
- Supports wide input voltage range suitable for battery-powered applications
- Includes controlled slew rate and status flag capabilities for system protection
Applications
- Portable electronic devices requiring step-up voltage conversion
- Battery-operated systems needing stable 3.3V output generation
- Compact consumer electronics with limited board space constraints
Procurement Notes
Verify the specific ordering suffix matches the required packaging format, as variations exist between tape-and-reel and cut-tape configurations. Confirm that the SC-74A package designation aligns with your PCB footprint requirements. Ensure compliance with RoHS3 standards if environmental regulations apply to your manufacturing process. Cross-reference the manufacturer part number BD2233GGTR-ND only if substituting components within the same family, noting that functional differences may exist between distinct product lines.
Selection Notes
Select this component when a compact synchronous boost solution is required for low-current applications up to 10mA. The integrated MOSFET design reduces external component count compared to asynchronous alternatives. Consider the 100kHz switching frequency for balancing size and efficiency. Verify input voltage compatibility with your power source, particularly for single-cell lithium-ion or alkaline battery configurations operating near the lower end of the specified range.
Part Context
This device belongs to Rohm's portfolio of power management integrated circuits designed for portable electronics. It complements other PMIC offerings by providing efficient voltage boosting in minimal footprint packages. The SC-74A form factor allows integration into space-constrained designs where traditional through-hole or larger surface-mount regulators cannot fit. It serves as a specialized solution for applications requiring precise voltage regulation from low-voltage sources.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility carefully when considering alternative manufacturers, as pinouts and electrical characteristics may differ significantly between synchronous boost converters.
