The BD9G401EFJ-ME2 is a single-channel switching voltage regulator with a 4.5V to 42V input range and a 3.5A FET from ROHM. It has an internal synchronous rectification function, adjustable output voltage from 0.8V to 37V, and provides 99% efficiency at low current. It also provides a power-saving current consumption of only 77µA and a maximum of 1.5µA when output voltage from the off-mode is 2.5V or less. This regulator also comes with protective features such as built-in overcurrent protection, overheat protection, and overvoltage protection. Additionally, it is RoHS Compliant and halogen-free. It is suitable for use in automotive, industrial, and other applications.
