Electrical Characteristics
Note: (1) ThetaJA is calculated from a package in still air, mounted to 3" x 4.5", 4 layer FR4 PCB with thermal vias under
exposed pad per JESD51 standards.
Unless specified: V
IN = 12V, VCOMP = 0.8V, VBST = VIN + 5V, EN = tied to VIN, SW = open.
T
A = TJ = -40°C to 125°C.
Absolute Maximum Ratings
Exceeding the specifications below may result in permanent damage to the device, or device malfunction. Operation outside of the parameters
specified in the Electrical Characteristics section is not implied. Exposure to Absolute Maximum rated conditions for extended periods of time may
affect device reliability.
