BD9G101G

General Description

The BD9G101G is high voltage input 42V step-down

switching regulator with integrated internal Power

MOSFET.

It provides maximum 0.5A output with small SSOP6

package.

It is allowing the use of small inductor by high frequency

operation of 1.5MHz. Also, it is implemented to downsize

by incorporation of phase compensation parts with

current mode.
