If the pad needs to be connected to other pins, it should be connected to the AGND pin. USP-10 (BOTTOM VIEW) ● Control Methods, MODE Pins, VD SENSE Pins * The XC9509A to F series' MODE pin switches either the regulator block or DC/DC block to stand-by mode. When the CE mode is off, every function except for the VD function enters into the stand-by mode. (The MODE pin does not operate independently.) MSOP-10 (TOP VIEW) |
