Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
ELECTRICAL CHARACTERISTICS
(V IN = +12V (for MAX5052, V IN must first be brought up to 23.6V for startup), 10nF bypass capacitors at V IN and V CC , C NDRV = 0,
V UVLO = +1.4V, V FB = +1.0V, V COMP = floating, V CS = 0V, typical values are measured at T A = +25°C, T A = -40°C to + 85°C, unless
otherwise noted.) (Note 1)
