NOTES: 1. Maximum package power dissipation limits must be observed.
4. This parameter is measured at the latch trip point with VFB = 0 V
NOTES: 2. Adjust VCC above the startup threshold before setting to 15 V.
NOTES: 3. Low duty cycle pulse techniques are used during test to maintain junction
NOTES: 3. temperature as close to ambient as possible:
ΔV Compensation
5. Comparator gain is defined as AV = ΔV Current Sense
