MAX20046 datasheet(4/18 Pages) MAXIM

4 / 18 page

Note 1: Specifications with minimum and maximum limits are 100% production tested at TA = +25°C and are guaranteed over the

operating temperature range by design and characterization. Actual typical values may vary and are not guaranteed.

Note 2: Forward current is defined as current into BUS and out of HVBUS. See the Functional Diagram.

Note 3: Guaranteed by design. Limits are not production tested.

Note 4: Tested in the Typical Application Circuit, as shown on the evaluation kit.

(VBUS = 5.0V VIN = +3.3V, TJ = TA = -40°C to +105°C. RL = ∞, unless otherwise noted. Typical values are at VEN = 0V or VEN = 3.3V

and TA = +25°C, unless otherwise noted.) (Note 1)
