BD9S110NUX-CE2

Overview

The BD9S110NUX-CE2 is a single-channel synchronous buck DC/DC converter from ROHM Semiconductor, designed for automotive applications. It features an input voltage range of 2.7 V to 5.5 V and provides a fixed output voltage of 1.2 V with a maximum output current of 1 A. The device operates at a switching frequency of up to 2.2 MHz and includes integrated power MOSFETs. It supports operation across a temperature range of -40 °C to +125 °C and is housed in a VSON-8 (VSON008X2020) package.

Feature Summary

Integrated low on-resistance power MOSFETs for synchronous rectification
Built-in feedback resistors and phase compensation circuits for minimal external components
Current mode control architecture enabling high-speed transient response
AEC-Q100 qualified for automotive functional safety support

Applications

Automotive electronic control units (ECUs)
Infotainment system power distribution
Sensor node power regulation
Body control module voltage conversion

Procurement Notes

Verify the specific suffix CE2 matches the required tape-and-reel quantity of 4000 units. Confirm that the fixed 1.2 V output aligns with the target load requirements, as alternative models like BD9S111NUX-CE2 offer different fixed voltages. Ensure the VSON-8 footprint compatibility with the PCB layout before finalizing the order.

Selection Notes

Select this component when a fixed 1.2 V rail is required for automotive loads drawing up to 1 A. The 2.2 MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the BD9S000NUX-CE2 if adjustable output or lower current (600 mA) suffices, or the BD9S201NUX-CE2 if higher current capacity (2 A) is necessary.

Part Context

This part belongs to the BD9S1xx series of ROHM's automotive-grade synchronous buck converters. It shares the VSON008X2020 package and 2.2 MHz switching architecture with peers like the BD9S111NUX-CE2, differing primarily in the internally set output voltage. The series is characterized by its integration of control logic and power stages to simplify design.
