7.5 Electrical Characteristics

Limits apply over T_A = –40°C to +105°C (EXT suffix device; T_A = –55°C to +105°C), V_IN = 24 V, V_OUT = 3.3 V, I_OUT = 1.5 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.

(1) The recommended minimum V_IN is 4.2 V or (VOUT + 600 mV), whichever is greater.

(2) The overall output voltage tolerance is affected by the tolerance of the external R_FBT and R_FBB resistors.

(3) The typical switching frequency of this device will change based on operating conditions. See the Switching Frequency section for more information.
