Overview
The BD9110NV-E2 is a synchronous buck switching regulator from ROHM Semiconductor, designed for high-efficiency step-down conversion. It operates with an input voltage range of 4.5V to 5.5V and delivers a maximum output current of 2A. The device integrates the controller and power MOSFETs in a compact SON8 package (5.0x6.0mm). It supports a switching frequency of 1MHz and features current-mode control for fast transient response. The component includes light load mode operation and an enable pin, functioning within an operating temperature range of -25°C to 105°C.
Feature Summary
- Integrates controller and synchronous rectification MOSFETs for compact design
- Utilizes current-mode control to ensure rapid transient response during load changes
- Incorporates pulse skipping technology to maintain high efficiency under light load conditions
Applications
- Generating low voltage rails from 5V or 3.3V power lines
- Portable electronic devices requiring efficient DC-DC conversion
- Industrial equipment power management systems
Procurement Notes
Verify the specific suffix E2 for RoHS compliance and lead-free status. Confirm the SON008V5060 package dimensions against your PCB footprint. Check the latest datasheet for any updates regarding the NRND status, as this indicates the component is not recommended for new designs. Ensure thermal management aligns with the specified operating temperature range.
Selection Notes
Select this component when a single-channel, high-efficiency buck converter is required for 5V input systems. It is suitable for applications needing up to 2A output current with minimal external components. Consider the integrated FET topology for space-constrained designs. Verify that the 1MHz switching frequency meets your electromagnetic interference requirements.
Part Context
The BD9110NV-E2 belongs to the BD91xx series of high-efficiency step-down switching regulators. This family focuses on generating low voltages from standard 5V or 3.3V sources using ROHM's unique pulse skipping and synchronous rectification technologies. The series emphasizes compactness and performance in portable and industrial applications.
Replacement Considerations
Check for BD9111NV-E2 for similar specifications. Review BD9130NV-E2 for adjustable output options. Consult official substitution lists for direct replacements.
