1 / 3 page BD9300/F/FV Regulators Rev.A 1/2 1-channel DC/DC converter controller BD9300/F/FV BD9300/F/FV is an output open collector type of 1-channel DC/DC converter controller. Step-up, step-down and inverting DC/DC converter can be composed. Input voltage range is wide (3.6V to 35V) and this IC can be used widely for various applications. Pin layout is nearly the same as BA9700 and it is easy to replace it.
