6.5 Electrical Characteristics

Limits apply over T_A = –40°C to +105°C, PV_IN= 12 V, V_IN = 12 V, V_OUT = 1.8 V, V_REF = 1.0 V, F_SW = 500 kHz, IOUT = 25 A, (unless otherwise noted); Minimum and maximum limits are specified through production test or by design. Typical values represent the most likely parametric norm and are provided for reference only.
