(TA = 25 °C, unless otherwise noted)
ELECTRICAL PARAMETER CONDITIONS LIMITS UNIT
PVIN, VIN Reference to PGND -0.3 to +28 SW / PH Reference to PGND -0.3 to +28 SW / PH (AC) Reference to PGND (100 ns) -8 to +33 BOOT -0.3 to VPH + PVCC BOOT to SW -0.3 to +6 V Drive supply voltage (PVCC) -0.3 to +6 Bias supply voltage (VDD) -0.3 to +6 AGND to PGND -0.3 to +0.3 All other pins Reference to AGND -0.3 to VDD + 0.3
Temperature
Junction temperature -40 to +150 °C Storage temperature -65 to +150
Power Dissipation
Junction-to-ambient thermal impedance (RthJA) 24 Thermal resistance from junction to case (RthJ-C) 4.5 °C/W Thermal resistance from junction to PCB (RthJ-PCB) 5
ESD Protection
HBM 2 kV Electrostatic discharge protection CDM 750 V 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.
RECOMMENDED OPERATING CONDITIONS
(all voltages referenced to GND = 0 V)
ELECTRICAL PARAMETER MIN. TYP. MAX. UNIT
