wise noted.) (Notes 1, 5)
Note 1: For the MAX1714B, AGND and PGND refer to a single pin designated GND.
Note 2: SKIP may be forced below -0.3V, temporarily exceeding the absolute maximum rating, disabling over/undervoltage fault
Note 3: When the inductor is in continuous conduction, the output voltage will have a DC regulation level higher than the error-
Note 4: On-time and off-time specifications are measured from 50% point to 50% point at the DH pin with LX = PGND, V
Note 5: Specifications to -40°C are guaranteed by design, not production tested.
