[ Product description ]

The BD9853AFV is a 2-ch synchronous DC/DC controller that can operate at a maximum switching frequency of 2MHz, enabling the use of a smaller external coil than conventional lower-frequency switching regulators. This makes the BD9853AFV a suitable choice for downsizing applications.
