(2) The Soft Start pin sources 50µA to an external capacitor. The converter operates in synchronous mode above the Soft Start transition threshold and in asynchronous mode below it. (4) This device is ESD sensitive. Use of standard ESD handling precautions is required. (5) 120ns maximum at 70°C. (6) Under pulsing condition, the negative voltage can be -5V for no more than 40ns measured from 50% falling to 50% rising. Unless Specified: V CC = 4.75 to 5.25V, GND = PGND = 0V, FB = VO, TJ = 25°C, VBSTC = VBST = 12V Electrical Characteristics (Cont.) |
