BD9E102FJ (Marking: 9E102) Technical Datasheet & Repair Guide

If you provide the manufacturer name or a photo of the component marking, I can narrow down the exact datasheet and its most useful specifications.

You will likely not find a direct PDF named 9e102.pdf . Instead, find the series datasheet that covers all capacitance values, including 102. 9e102 datasheet

The output voltage is configured by setting a resistor divider network ( RTOPcap R sub cap T cap O cap P end-sub

Error amplifier output. Used for loop phase compensation networks. Power ground return path for the low-side internal switch. SW

The 9E102 is a Hall Effect sensor, which is a type of non-contact sensor that detects changes in magnetic fields. It's commonly used in applications such as proximity sensing, position sensing, and current sensing. The output voltage is configured by setting a

One of the standout features of the BD9E102FJ is its SLLM™ control. This technique optimizes efficiency during light-load conditions by reducing switching losses. In many traditional DC/DC converters, efficiency drops significantly when the output current falls below a certain threshold. The SLLM™ mode automatically adjusts the operating mode to maintain high efficiency across the entire load range, making the device ideal for battery-powered and always-on applications where standby power consumption is critical.

– Regulated internal supply rail. Requires decoupling capacitors (e.g., 0.1μF to 10μF) close to the pin to filter high-frequency switching noise. Typical Application Circuit Architecture

It typically includes over-current protection (OCP), thermal shutdown (TSD), and under-voltage lockout (UVLO) to prevent damage during fault conditions. Common Applications SW The 9E102 is a Hall Effect sensor,

(Note: Specific variants may differ based on batch codes. Verify exact suffix with supplier.)

Replacing an SOP-8 component requires precision. Technicians recommend using a at approximately 250°C to 260°C to avoid lifting traces or delaminating the PCB. Always verify the surrounding MOSFETs for shorts before installing a new 9E102, as a shorted MOSFET will instantly destroy your new controller.

.
