Note 1: The MAX17003/MAX17004 cannot operate over all combinations of frequency, input voltage (V IN ), and output voltage. For
large input-to-output differentials and high switching-frequency settings, the required on-time may be too short to maintain
the regulation specifications. Under these conditions, a lower operating frequency must be selected. The minimum on-time
must be greater than 150ns, regardless of the selected switching frequency. On-time and off-time specifications are mea-
sured from 50% point to 50% point at the DH_ pin with LX_ = GND, V BST_ = 5V, and a 250pF capacitor connected from
DH_ to LX_. Actual in-circuit times may differ due to MOSFET switching speeds.
Note 2: When the inductor is in continuous conduction, the output voltage has a DC-regulation level lower than the error-comparator
threshold by 50% of the ripple. In discontinuous conduction ( SKIP = GND, light load), the output voltage has a DC regula-
tion level higher than the trip level by approximately 1% due to slope compensation.
Note 3: Specifications from -40°C to +85°C are guaranteed by design, not production tested.
