UNIT

Note 1: Maximum package power dissipation limits must be observed.

Note 3: Adjust VCC above the Start-Up threshold before setting to 15V.

Note 4: This parameter is measured at latch trip point with VFB=0V.

Note 5: Comparator gain is defined as:

AV =

Note 6: These parameters are guaranteed by design but not 100% tested

in production.

Note 7: Low duty cycle pulse techniques are used during test to main-

tain junction temperature as close to ambient as possible: Tlow=0°C ;

Thigh=+70°C
