Overview
The BD9V101MUF-LBE2 is a synchronous buck DC/DC converter featuring integrated high-voltage power MOSFETs. It supports an input voltage range of 16 V to 60 V and delivers a maximum output current of 1 A. The device utilizes Nano Pulse Control technology, enabling a switching frequency up to 2.3 MHz with a minimum switch ON time of 20 ns. This allows direct conversion from high voltages, such as 60 V to 3.3 V, using minimal external components. The output voltage is adjustable from 0.8 V to 5.5 V.
Feature Summary
- Integrates high-voltage power MOSFETs for compact design
- Nano Pulse Control enables ultra-short minimum ON time
- Supports wide input voltage range suitable for industrial applications
- Includes comprehensive protection features including overcurrent and thermal shutdown
Applications
- Industrial equipment power supplies
- Direct 60V to 3.3V microcontroller voltage conversion
- Automotive systems requiring robust power management
Procurement Notes
Verify the specific suffix LBE2 against the manufacturer's latest datasheet to confirm package type and tape/reel specifications. Ensure compatibility with RoHS directives if required by your application standards. Cross-reference the part number with official ROHM distributors to confirm availability and lead times before finalizing procurement plans.
Selection Notes
Select this component when a wide input voltage range up to 60 V is required in a small footprint. It is suitable for designs needing high efficiency at high switching frequencies. Consider the integrated MOSFETs to reduce external component count. Verify that the thermal performance meets the system requirements under maximum load conditions.
Part Context
This part belongs to the BD9V101 series of synchronous buck converters from ROHM Semiconductor. It is designed for automotive and industrial markets, offering long-term supply stability. The series leverages Nano Pulse Control technology to achieve high performance in a compact VQFN package.
Replacement Considerations
Check for compatible parts within the BD9V101 family or other ROHM synchronous buck converters with similar input/output specifications. Ensure pinout compatibility and electrical parameters match before substitution.
