BD9P305EFV-CE2

Overview

The BD9P305EFV-CE2 is a synchronous buck DC/DC converter from ROHM Semiconductor, designed for automotive applications. It operates with an input voltage range of 3.5 V to 40 V and provides a single adjustable output from 0.8 V to 8.5 V at up to 3.0 A. The device features a selectable switching frequency of 2.2 MHz or 440 kHz and includes a shutdown function. It functions within a temperature range of -40°C to +125°C and is housed in an HTSSOP-20 package.

Feature Summary

• Integrates power MOSFETs for a compact synchronous buck topology
• Supports selectable switching frequencies for optimized efficiency and EMI performance
• Includes soft-start functionality to limit inrush current during startup
• Features a shutdown pin for system power management

Applications

• Automotive sensor power supplies
• ADAS camera module regulation
• Radar system power distribution
• In-vehicle infotainment subsystems

Procurement Notes

Verify the specific suffix CE2 against the manufacturer's latest datasheet to confirm pinout and thermal characteristics. Ensure the ordering part number matches the required packaging format. Cross-reference the RoHS compliance status directly with official documentation before procurement.

Selection Notes

Select this component when a high-current buck converter is needed for 42V automotive systems. The adjustable output allows flexibility for various logic levels. Consider the HTSSOP-20 package for thermal dissipation requirements relative to the 3A load capability.

Part Context

This IC belongs to the BD9P series of Nano Pulse Control™ converters. These devices are engineered for automotive primary DC/DC conversion, offering high reliability and wide input voltage tolerance suitable for harsh vehicle environments.

Replacement Considerations

Check for BD9P308MUF-CE2 if a different package is required. Verify functional compatibility with BD9P208MUF-CE2 for lower current needs.
