Overview
The BD9P205EFV-CE2 is a synchronous buck DC/DC converter IC from ROHM Semiconductor, designed for automotive applications. It features Nano Pulse Control technology and operates with an input voltage range of 3.5 V to 40 V. The device provides a single adjustable output voltage between 0.8 V and 8.5 V, delivering a maximum output current of 2 A. It supports a switching frequency up to 2.2 MHz and includes spread spectrum functionality for EMI reduction. The component functions within a temperature range of -40°C to +125°C and is housed in an HTSSOP-B20 package.
Feature Summary
- Integrates controller and power FETs using Nano Pulse Control technology for high efficiency and stable step-down ratios.
- Includes spread spectrum function to reduce electromagnetic interference (EMI) noise.
- Provides fast response performance to maintain stable power supply during battery start-up conditions.
Applications
- Automotive ADAS sensors including cameras and radar systems
- Vehicle infotainment and instrument cluster displays
- Body Control Modules (BCM)
Procurement Notes
Verify the specific suffix CE2 against the manufacturer's official datasheet to confirm pinout compatibility and functional specifications. Ensure the HTSSOP-B20 package dimensions match your PCB footprint requirements. Confirm that the selected variant meets the required AEC-Q100 qualification standards for your target automotive application environment.
Selection Notes
Select this component when designing primary DC/DC converters for automotive systems requiring high reliability and compact size. It is suitable for applications demanding wide input voltage tolerance and low EMI emissions. Consider the integrated FET topology for simplified design and reduced bill of materials compared to discrete solutions.
Part Context
This part belongs to the BD9P series of ROHM Semiconductor, which are primary DC/DC converter ICs rated for 42V withstand voltage. The series is engineered to balance high-speed response with high efficiency, specifically targeting the stringent demands of modern automotive electronics such as advanced driver assistance systems.
Replacement Considerations
The BD9P205MUF-CE2 is a documented alternative offering identical electrical characteristics but utilizing a VQFNFV4040-EP-20 package instead of the HTSSOP-B20 form factor. Verify mechanical fit before substitution.
