Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
To calculate maximum switch “on” voltage at currents between
low and high conditions, a linear interpolation may be used.
Note 3:
A feedback pin voltage (V
FB
) of 2.5V forces the V
C
pin to its low
clamp level and the switch duty cycle to zero. This approximates the zero
load condition where duty cycle approaches zero.
Note 4:
Total voltage from V
IN
pin to ground pin must be
≥
8V after start-
up for proper regulation.
Note 5:
Switch frequency is internally scaled down when the feedback pin
voltage is less than 1.3V to avoid extremely short switch on times. During
testing, V
FB
is adjusted to give a minimum switch on time of 1
μ
s.
