Fig.38 Soft Start Configuration

Connecting an external capacitor to the GATE terminal of the BD2270HFV makes it possible to slow the rise of the N-channel

MOSFET, thus achieving reduction of the inrush current to the large-capacity capacitor mounted on the load side.

● Application Information

This system connection diagram gives no warranty to the operation as application.

To change the external circuit constant or else and use this IC, determine the application allowing for an adequate margin

with consideration given to variations in external parts and ICs including not only static characteristics but also transient

characteristics.
