Note: 1. Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient

as possible.

2. This parameter is measured at the latch trip point with VFB=0V.

3. Comparator gain is defined as:

ΔV Output Compensation

AV=

ΔV Current Sense Input

4. Adjust VCC above the startup threshold before setting to 15V.
