Excellent power-saving mode when active, and 0 µA (Typ.) in shutdown. 9e102 datasheet
The BD9E102FJ-E2 and the BD9E102FJ-EVK-001 evaluation board are by ROHM and major distributors like DigiKey. For new designs, ROHM recommends newer pin-compatible or upgraded parts from the same family such as the BD9E100FJ-LB.
Check the feedback node () against ground. If it is shorted, downstream components like the chipset or processor may have suffered over-voltage damage. Rework & Replacement Guide Power supply input pin
If you are looking for specific application notes, I can check if the user guide provides more information. If you're designing a board, I can also help find the typical PCB layout or recommended external component values for different input/output voltages. Let me know what you need. DC/DC Converter Application Information
Often found in 1210 (3225 Metric) or 2220 (5650 Metric) surface-mount footprints. This link or copies made by others cannot be deleted
manufactured by ROHM Semiconductor . This integrated circuit (IC) is a critical component in power management systems, designed to efficiently convert higher input voltages into stable, lower output voltages for sensitive electronic devices. Functional Overview and Architecture
Note: For multi-tap versions, each tap output toggles sequentially with the specified increment.
