EVALUATION BOARD TERMINALS Terminal Function VIN Positive DC input voltage GND Common DC return VOUT Regulated DC output voltage EN/SYNC Enable and synchronization input Table 2. ABSOLUTE MAXIMUM RATINGS (Voltages are with respect to GND) Rating Value Unit DC Supply Voltage (VIN) 0.3 to 40 V DC Supply Voltage (EN, SYNC) 0.3 to 6 V Peak Transient Voltage (Load Dump on VIN) 45 V Junction temperature 40 to 150 C Ambient temperature (evaluation board) 40 to 105 C Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. Table 3.
