ELECTRICAL CHARACTERISTICS (continued)
Note 1: Dropout voltage is guaranteed by the p-channel switch resistance and assumes a maximum inductor resistance of 45m Ω .
Note 2: The PWM-skip-mode transition has approximately 10mA of hysteresis.
Note 3: The maximum output current is guaranteed by the following equation:
I LIM ?
1 + ( R N + R L )
where:
I OUT ( MAX ) =
V OUT (1 ? D)
2 x f x L
( 1 ? D )
2 x f x L
D =
V OUT + I OUT(MAX ) (R N + R L )
V IN + I OUT ( MAX ) ( R N ? R P )
and
R N = n-channel synchronous rectifier R DS(ON)
R P = p-channel power switch R DS(ON)
R L = external inductor ESR
I OUT(MAX) = maximum required load current
f = operating frequency minimum
L = external inductor value
I LIM can be substituted for I OUT(MAX) (desired) when solving for D. This assumes that the inductor ripple current is
small relative to the absolute value.
Note 4: POK only indicates the status of supplies that are enabled (except V7). When a supply is turned off, POK does not trigger
low. When a supply is turned on, POK immediately goes low until that supply reaches regulation. POK is forced low when all
supplies (except V7) are disabled.
Note 5: Specifications to -40°C are guaranteed by design, not production tested.
