BD90620EFJ-CE2

Overview

The BD90620EFJ-CE2 is a single-channel step-down switching regulator from ROHM Semiconductor, designed for automotive applications. It features an integrated power MOSFET and controller in a buck topology. The device supports an input voltage range of 3.5 V to 36 V with a maximum output current of 2.5 A. Output voltage is adjustable from 0.8 V to 36 V. The switching frequency can be set externally up to 600 kHz. It operates within a temperature range of -40°C to +125°C and is housed in an HTSOP-J8 package.

Feature Summary

Integrates high-voltage power MOSFET and controller for compact design
Supports external synchronization with clock signals
Includes soft start function to limit inrush current
Provides overcurrent protection for load safety

Applications

Automotive infotainment systems
Telematics control units
Body electronics power distribution
Industrial DC-DC conversion

Procurement Notes

Verify the exact suffix CE2 matches the required HTSOP-J8 package and taping specifications. Confirm AEC-Q100 Grade 1 qualification aligns with target automotive reliability standards. Check functional safety classification if system-level analysis is required. Ensure input/output voltage ranges suit the specific circuit design constraints before ordering.

Selection Notes

Select this component when a single-channel buck converter with integrated FET is needed for automotive environments. It is suitable for designs requiring wide input voltage tolerance up to 36 V. Choose this part if external frequency setting and synchronization capabilities are necessary for noise management. Verify that the 2.5 A output current meets the load requirements without exceeding thermal limits in the chosen enclosure.

Part Context

This regulator belongs to ROHM's automotive-grade PMIC portfolio, specifically the BD90620 series. It is engineered for high reliability in harsh automotive electrical environments. The device complements other ROHM solutions by offering integrated power stages to reduce external component count. It is distinct from linear regulators like the BD900N1EFJ due to its switching efficiency.
