ABSOLUTE MAXIMUM RATINGS
DC ELECTRICAL CHARACTERISTICS
(VCC = 3.0V, VGND = 0V, CIN = 0.1F from IN to GND, RL = infinity to GND, FB shorted to OUT, VSHDN = 3.0V, TA = -40°C to +85°C
(MAX4090E), TA = -40°C to +125°C (MAX4090A). Typical values are at TA = +25°C, unless otherwise noted.) (Note 2)
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: VCLP is the input clamp voltage as defined in the DC Electrical Characteristics table.
VCC to GND ............................................................. -0.3V to +6V
OUT, FB, SHDN to GND............................ -0.3V to (VCC + 0.3V)
IN to GND (Note 1) ................................... VCLP to (VCC + 0.3V)
