Notes
(1) Be sure to set the capacitance of the power supply bypass capacitor, C1, so that the ripple current of the capacitor,
(2) Chopping operations based on F3 and F4 are used for current control. The timing given below is used for OUT1 or
(3) Do not connect the N.C pins (5, 11, 12 pin) shown in the internal block diagram or sample application circuit to a
(4) Sample Timing Diagram
(5) If the current detection resistor, Rs, connected to pin1, pin2, and pin3 is short-circuited, the overcurrent detection
