4CH Internal Power MOSFET System Switching Regulator - BD9866GUL

BD9866GUL is a 4ch DC/DC converter IC composed of Buck converter 3-channels and Buck-Boost converter 1-channel.Including power MOSFET of all channels reduces the number of peripheral devices. Each channel is controlled individually, that enables to reduce power consumption of not working channel.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
