(1)

The minimum PVIN is 4.5 V or (VOUT / 0.75), whichever is greater. For VOUT = 3.3 V, the minimum PVIN is 4.75 V when IOUT > 1.5 A.

(2)

The stated limit of the set-point voltage tolerance includes the tolerance of both the internal voltage reference and the internal

adjustment resistor. The overall output voltage tolerance will be affected by the tolerance of the external RSET resistor.

(3)

Guaranteed by design. Not production tested.

6.5 Electrical Characteristics

Over -40°C to +105°C free-air temperature, PVIN = 24 V, VOUT = 5 V, IOUT = IOUT max, ƒsw = 500 kHz,

CIN1 = 1 x 10-µF, 100-V 1210 ceramic, CIN2 = 1 x 100-µF 100-V electrolytic bulk, and COUT = 3 x 47-µF, 16-V 1210 ceramic

(unless otherwise noted).
