ISL78206 Datasheet, PDF (8/19 Pages) Intersil Corporation – 40V 2.5A Buck Controller with Integrated High-side 40V 2.5A Buck Controller with Integrated High-side

ISL78206
Electrical Specifications Refer to “Block Diagram” on page 4 and Typical Application Schematics on page 5. Operating Conditions
Unless Otherwise Noted: V_IN = 12V, or V_CC = 4.5V, 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)
