9e102 Datasheet Link

is a specialized evaluation board designed for the BD9E102FJ, a synchronous buck converter manufactured by ROHM Semiconductor. This high-performance device is designed for industrial and consumer electronics requiring efficient step-down power conversion.

The evaluation board BD9E102FJ-EVK-001 is priced at approximately $46.43 USD from DigiKey, while production quantities of the IC itself are priced lower, with single-unit pricing around $0.29 from some distributors in high volumes.

The BD9E102FJ is offered in an 8-pin SOP-J8 package. The pinout is essential for correct PCB layout and device operation:

Years passed. The module’s edges wore. Its amber pin dimmed more often and required the warmth of a human hand to wake. Mara’s hair greyed at the temples. She had saved some small things—a photograph that had otherwise rotted in a flood, the timbre of a singer’s voice—and in so saving she had also made choices about what the world would continue to remember. 9e102 datasheet

The 9E102 utilizes a to achieve rapid transient responses and simplify phase compensation network design. By integrating both the high-side and low-side power MOSFETs into a single piece of silicon, it eliminates the need for an external Schottky diode, shrinking the total Printed Circuit Board (PCB) footprint and lowering the overall bill of materials (BOM) cost.

The GND pin and exposed pad should connect to the ground plane with multiple vias to manage heat, as the 1A load can cause the IC to warm up.

Specifically, the BD9E102FJ achieves 80% efficiency even at an output current as low as 10mA, a level where many competitors exhibit much lower performance.

The synchronous architecture of the BD9E102FJ delivers high efficiency across a wide load range. As shown in the RS Components evaluation report, when converting 24V down to 5.0V, the converter achieves efficiencies near 90%. The BD9E102FJ is offered in an 8-pin SOP-J8 package

Enable Control. Driving this pin above 2.0V turns the regulator on; pulling it below 0.8V forces the IC into a 0 µA shutdown state. Do not leave this pin floating.
