ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

(Circuit of Figure 1, VIN = 10V, VCC = VDD = VSHDN = VPGDIN = VPSI = VILIM = 5V, V3P3 = 3.3V, DPRSLPVR = GNDS = GND, VCSP1

= VCSN1 = VCSP2 = VCSN1 = 1.0000V, FB = FBAC, RFBAC = 3.57kΩ from FBAC to CSN1, D6–D0 = [0101000]; MAX17082/MAX17482:

VSLOW = 5V; MAX17021: DPRSTP = GND; TA = 0°C to +85°C, unless otherwise noted. Typical values are at TA = +25°C.)

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.

Note 1:

SHDN might be forced to 12V for the purpose of debugging prototype boards using the no-fault test mode, which disables

fault protection and overlapping operation.
