Overview
The BD9130NV-E2 is a synchronous step-down switching regulator IC manufactured by Rohm Semiconductor. It features an adjustable output voltage range from 1V to 2.5V with a maximum continuous output current of 2A. The device operates with an input voltage supply between 2.7V and 5.5V. It utilizes a fixed switching frequency of 1MHz and employs current-mode control for fast transient response. The integrated circuit is housed in an 8-VDFN package with a bare pad, measuring 5.0mm x 6.0mm, and supports an operating temperature range from -25°C to 105°C.
Feature Summary
- Synchronous rectification topology for improved efficiency across load ranges
- Current-mode control architecture enabling rapid transient response during load changes
- Integrated power MOSFETs and controller within a compact surface-mount package
Applications
- Generating low voltage rails from 5V or 3.3V power lines
- Portable electronic devices requiring efficient DC-DC conversion
- Industrial applications utilizing standard 5V input supplies
Procurement Notes
Verify the specific ordering suffix matches the required tape and reel quantity. Confirm that the 8-VDFN package dimensions align with PCB footprint requirements. Ensure the supplier provides official datasheets confirming the 1V minimum output capability. Check for RoHS compliance documentation if environmental standards are mandatory for the production line.
Selection Notes
Select this component when a 2A output current is sufficient for the target load. The 1MHz switching frequency allows for smaller external passive components compared to lower frequency alternatives. The wide input voltage range accommodates standard 5V systems. Consider thermal performance due to the small package size when designing for high ambient temperatures.
Part Context
This part belongs to the BD91x series of high-efficiency step-down regulators designed by Rohm. The series focuses on producing low voltages such as 1V from common 5V or 3.3V sources. The BD9130NV-E2 variant specifically offers adjustable output settings within the 1V to 2.5V window, distinguishing it from fixed-output counterparts in the same family.
Replacement Considerations
The BD9130NV is the base model without the E2 suffix. Verify if the E2 suffix indicates specific environmental or packaging variations. No direct cross-manufacturer equivalents are confirmed in the provided data.
