Overview
The BD9152MUV-E2 is a dual synchronous buck switching regulator manufactured by ROHM Semiconductor. It operates within an input voltage range of 4.5 V to 5.5 V and provides two independent output channels, each capable of delivering up to 1.5 A. The adjustable output voltage spans from 800 mV to 2.5 V. Key electrical specifications include a fixed switching frequency of 1 MHz and a typical quiescent current of 10 uA. The device is housed in a compact VQFNV4040-EP-20 surface-mount package and supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Dual-channel architecture providing independent step-down conversion for multiple power rails
- Integrated synchronous MOSFETs for high efficiency across the load range
- Low quiescent current consumption to enhance system power savings during standby
Applications
- Portable electronic devices requiring dual voltage rails
- Embedded systems with strict power budget constraints
- Industrial control modules utilizing standard 5V input supplies
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status via official datasheets. Ensure storage conditions align with manufacturer guidelines to maintain solderability and performance integrity before assembly.
Selection Notes
Select this component when dual isolated outputs are required from a single 5V source. The 1.5 A per channel rating suits moderate load applications. Verify that the 1 MHz switching frequency fits EMI requirements and inductor size constraints compared to lower-frequency alternatives.
Part Context
This part belongs to the BD9152MUV series of dual step-down regulators. It shares the VQFNV4040-EP-20 package form factor with other members like the BD9150MUV-E2, though electrical parameters such as input voltage range and switching frequency may differ across the family.
Replacement Considerations
BD9150MUV-E2 offers similar dual-output functionality but operates at a higher minimum input voltage of 4.75 V and uses a 1.5 MHz switching frequency.
