Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional

operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to

absolute maximum rating conditions for extended periods may affect device reliability.

ELECTRICAL CHARACTERISTICS (continued)

Note 1: Dropout voltage is guaranteed by the p-channel switch resistance and assumes a maximum inductor resistance of 45mΩ.

Note 2: The PWM-skip-mode transition has approximately 10mA of hysteresis.

Note 3: The maximum output current is guaranteed by the following equation:

1

OUT

I_LIM

2 x f x L

I_OUT(MAX)

1

x f x L

where:

V_OUT+ I_OUT(MAX)(R_N+ R_L)

D =

V_IN+ I_OUT(MAX)(R_N− R_P)

and

R = n-channel synchronous rectifier R

N DS(ON)

R = p-channel power switch R

P

DS(ON)

R = external inductor ESR

L

I

= maximum required load current

OUT(MAX)

f = operating frequency minimum

L = external inductor value

I

can be substituted for I

(desired) when solving for D. This assumes that the inductor ripple current is

LIM

OUT(MAX)

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.
