6 / 65 page Pin settings L6985F 6/65 DocID027836 Rev 2 2.3 Maximum ratings Stressing the device above the rating listed in Table 2: Absolute maximum ratings may cause permanent damage to the device. These are stress ratings only and operation of the device at these or any other conditions above those indicated in the operating sections of this specification is not implied. Exposure to absolute maximum rating conditions may affect device reliability. 12 PGND Power GND 13 LX Switching node 14 LX Switching node 15 VIN DC input voltage 16 VBIAS Typically connected to the regulated output voltage. An external voltage reference can be used to supply a part of the analog circuitry to increase the efficiency at the light-load. Connect to GND if not used. - E. p.
