manufacturer:linear description:floating bootstrap supply for the upper mosfet. a capacitor connected between bst and sw pins holds this bootstrapped voltage for the high side mosfet as it is switched. the capacitor should be chosen between 100 nf and 1 f. logic-level input signal that has primary control of the drive outputs. no connection input supply. this pin should be bypassed to pgnd with ~1 µf ceramic capacitor. synchronous rectifier drive. output drive for the lower (synchronous rectifier) mosfet. power ground. should be closely connected to the source of the lower mosfet. this pin is connected to the buck-switching node, close to the upper mosfets source. it is the floating return for the upper mosfet drive signal. it is also used to monitor the switched voltage to prevent turn- on of the lower mosfet until the voltage is below ~1 v. thus, according to operating conditions, the high low transition delay is determined at this pin. buck drive. output drive for the upper (buck) mosfet. |
