Note 4:
Switch current limit guaranteed by design and/or correlation to
static tests. Duty cycle affects current limit due to ramp generator (see
Block Diagram).
Note 5:
Bias current flows out of LBI pin.
Note 6:
Connect the four GND pins (Pins 4–7) together at the device.
Similarly, connect the three SW pins (Pins 8–10) together and the two V
IN
pins (Pins 11, 12) together at the device.
Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
The LT1308ACS8 and LT1308BCS8 are designed, characterized
and expected to meet the industrial temperature limits, but are not tested
at –40
°
C and 85
°
C. I grade devices are guaranteed.
Note 3:
Bias current flows into FB pin.
