Patched — 9e102 Datasheet

Engineers should ensure adequate PCB copper area for heat sinking, particularly when operating at high input voltages and near the full 1A output current.

The BD9E102FJ integrates several key features that simplify power supply design and enhance system reliability: 9e102 datasheet

The ROHM BD9E102FJ is a current-mode, synchronous buck DC/DC converter designed to deliver up to 1A of output current from a wide input voltage supply, all in a compact SOP-J8 surface-mount package. It is engineered for applications requiring high efficiency, particularly at light loads, and features a simple, external-component-friendly design. Engineers should ensure adequate PCB copper area for

The 9E102 IC is engineered for highly efficient buck conversion. When servicing a damaged board—often signaling a failure through short circuits across VINcap V sub cap I cap N end-sub The 9E102 IC is engineered for highly efficient

Use a 9E102 in series with a 100 Ω resistor across relay contacts or a triac to suppress voltage spikes (dI/dt). For 24V AC or DC circuits, the 50V rating is sufficient. For 110V AC, select the 100V variant.
