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
detection for the purpose of debugging prototypes (Figure 6). Limit the current drawn to 5mA maximum.
Note 3: When the inductor is in continuous conduction, the output voltage will have a DC regulation level higher than the error-
comparator threshold by 50% of the ripple. In discontinuous conduction ( SKIP = AGND, light-loaded), the output voltage
will have a DC regulation level higher than the trip level by approximately 1.5% due to slope compensation.
Note 4: On-time and off-time specifications are measured from 50% point to 50% point at the DH pin with LX = PGND, V BST = 5V,
and a 250pF capacitor connected from DH to LX. Actual in-circuit times may differ due to MOSFET switching speeds.
Note 5: Specifications to -40°C are guaranteed by design, not production tested.
