For a 5V output from a 12V–24V input, you need: one 6.2µH to 10µH power inductor, one 10µF 35V ceramic input capacitor, one 22µF 10V ceramic output capacitor, two resistors for the feedback divider (e.g., 5.6kΩ and 10kΩ), and one bootstrap capacitor.

The IC is primarily used in consumer electronics for power management: Laptop Motherboards 9e102 datasheet
Mara smoothed the page. The datasheet read less like a manual and more like instruction for grief:
Mara waited for the knock at the door that meant someone had come with a request or a threat. None came. She was left with the ways she'd chosen to save and the ones she had declined. She did not know if the crate had been reclaimed by those who had made it or if someone had found the module dormant and decided to wake it. Perhaps it traveled to a lab that would dissect it in the name of safety, or perhaps it was taken to a shelf beside other things that had been deemed too dangerous for regular use. For a 5V output from a 12V–24V input, you need: one 6
The loop connecting the input capacitor, IC, and diode must be as small as possible to reduce switching noise.
In the evenings, when the city polished its metal and the warehouse lights were turned down, the module would hum softly and project tiny films across the ceiling—snippets of lives connected only by the module’s passage through them. Mara watched these like a curfew. One projection lingered longer than usual: a child on a swing at dusk, gripping the chains with small, determined hands. The camera pulled back and the horizon was not a coastline or a city but a machine—huge, elliptical, stitched with a lattice of bronzed veins. The child looked up and the machine’s surface rippled like water. Someone in the projection—an adult—said a single sentence in a language Mara did not know. The module translated not words but intent: preserve. The datasheet read less like a manual and
In UK legislation, “9E102” appears as a technical note identifier related to . The classification specifically states: “In 9E102 ‘UAV’ means unmanned aerial vehicle systems capable of a range exceeding 300 km”. If your application involves aerospace or defense, you must check for this regulatory context. However, this is not related to the semiconductor device.
The BD9E102FJ comes in a compact SOP-J8 package, requiring proper PCB layout for heat dissipation. 4. Operation Procedures (Evaluation Board)
Works alongside OCP by triggering a frequency foldback or hiccup sequence when the feedback voltage drops significantly.
