BD9060F-CE2

Overview

The BD9060F-CE2 is a single-channel buck switching regulator from ROHM Semiconductor, designed for automotive applications with AEC-Q100 Grade 1 qualification. It integrates a P-channel power MOSFET and controller in an SOP-8 package. The device supports an input voltage range of 5V to 35V and delivers up to 2A output current. Output voltage is adjustable from 800mV to 35V. The switching frequency is externally programmable between 200kHz and 500kHz via external resistors, with high precision of ±5%. It features external synchronization capability, soft start, overcurrent protection, and thermal shutdown.

Feature Summary

• Integrates a high-voltage P-channel POWER MOSFET and control circuitry to minimize external component count.
• Allows flexible operation through external resistor setting for switching frequency within the 200kHz to 500kHz range.
• Supports synchronization with an external clock signal via a dedicated input terminal.
• Includes built-in safety mechanisms such as overcurrent protection and thermal shutdown circuits.

Applications

• Automotive infotainment systems
• Instrument cluster power supplies
• Body electronics modules
• Telematics units

Procurement Notes

Verify the specific suffix 'E2' corresponds to the tape-and-reel packaging configuration required for your assembly line. Confirm that the AEC-Q100 Grade 1 qualification meets your vehicle's functional safety requirements. Ensure the SOP-8 footprint matches your PCB design guidelines. Check for any recent lifecycle status updates or recommended new designations from ROHM Semiconductor before finalizing procurement.

Selection Notes

Select this component when a robust, high-input voltage buck converter is needed for automotive environments. The integrated P-channel FET simplifies design compared to N-channel alternatives requiring bootstrap drivers. The wide input range accommodates typical automotive load dump conditions. External frequency setting allows optimization for EMI performance. Verify that the 2A continuous current rating suffices for the target application's peak loads.
