Electrical Specifications Refer to “Block Diagram” on page 14 and “Typical Application Schematics” on page 4. Operating Conditions
Unless Otherwise Noted: V_PVIN = 12V, or V_AVINO = 4.5V ±10%, T_A = -40°C to +105°C. Typicals are at T_A = +25°C. Boldface limits apply across the
operating temperature range, -40°C to +105°C. (Continued)
