6.5 Electrical Characteristics

Limits apply over T_A = –40°C to +105°C, V_IN = 24 V, V_OUT = 5 V, I_OUT = I_OUT maximum, f_sw = 500 kHz, FPWM mode (unless otherwise noted); C_IN1 = 3x 10 µF, 50-V, 1210 ceramic; C_IN2 = 2x 4.7 µF, 50-V, 1210 ceramic; C_OUT = 6x 22 µF, 25-V, 1210 ceramic. 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) For output voltages ≤ 5 V, the recommended minimum V_IN is 3.5 V or (V_OUT + 1 V), whichever is greater. For output voltages > 5 V,
the recommended minimum V_IN is (1.1 × V_OUT). See Voltage Dropout for more information.

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