ADP3051 ABSOLUTE MAXIMUM RATINGS Table 2. Parameter Rating
IN, SHDN, COMP, SW, FB to GND –0.3 V to +6 V Stresses above those listed under Absolute Maximum Ratings SW to IN –6 V to +0.3 V may cause permanent damage to the device. This is a stress rat- PGND to GND –0.3 V to +0.3 V ing only; functional operation of the device at these or any Operating Ambient Temperature –40°C to +85°C other conditions above those indicated in the operational sec- Operating Junction Temperature –40°C to +125°C tions of this specification is not implied. Exposure to absolute Storage Temperature –65°C to +150°C maximum rating conditions for extended periods may affect θ device reliability. Absolute maximum ratings apply individually JA, 2-Layer (SEMI standard board) 159°C/W θ only, not in combination. Unless otherwise specified, all other JA, 4-Layer (JEDEC standard board) 116°C/W Lead Temperature Range voltages are referenced to GND. Soldering (10 sec) 300°C Vapor Phase (60 sec) 215°C Infrared (15 sec) 220°C
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although this product features pro- prietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electro- static discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
