Overview
The BD9F500QUZ-E2 is a single synchronous buck DC/DC converter from ROHM Semiconductor, featuring integrated power MOSFETs and Nano Pulse Control™ technology. It supports an input voltage range of 4.5 V to 36 V and delivers up to 5 A output current with adjustable output voltages from 600 mV to 14 V. The device operates at switching frequencies of 600 kHz, 1 MHz, or 2.2 MHz and maintains a low quiescent current of 20 uA. Designed for operation between -40°C and +85°C, it utilizes a compact VMMP16LZ3030 package.
Feature Summary
- Integrates high-side P-channel and low-side N-channel MOSFETs within a single chip to minimize external component count.
- Employs Nano Pulse Control™ architecture to achieve fast transient response and optimized light-load efficiency.
- Includes comprehensive protection mechanisms such as over-current protection, thermal shutdown, and under-voltage lockout.
Applications
- Portable electronic devices requiring efficient step-down conversion
- Industrial control systems needing stable power regulation
- Communication equipment utilizing wide input voltage ranges
Procurement Notes
Verify the specific suffix E2 against the manufacturer's latest datasheet to confirm pin compatibility and RoHS status. Confirm availability as the part may be subject to end-of-life notices. Ensure the VMMP16LZ3030 package footprint matches your PCB design constraints before finalizing orders.
Selection Notes
Select this component when a wide input voltage range up to 36 V is required alongside high current capability. The integrated MOSFET design simplifies layout compared to discrete solutions. Consider the available switching frequency options to balance efficiency requirements against electromagnetic interference constraints in your specific application environment.
Part Context
This device belongs to the BD9x500 series of synchronous buck converters. The series is characterized by built-in power MOSFETs and constant on-time control methods designed for rapid transient responses. These ICs are engineered to support low inductance designs while maintaining high efficiency across varying load conditions.
Replacement Considerations
Check for direct substitutes within the BD9F500 series or other ROHM synchronous buck converters with similar 5 A ratings and compatible packages. Verify that any replacement maintains the required input voltage range and switching frequency settings.
