NOTES: 1. Maximum package power dissipation limits must be observed.
2. Adjust VCC above the startup threshold before setting to 15 V.
3. Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient as possible:
Tlow = 0°C for the MC34065
Thigh = +70°C for MC34065
Tlow = –40°C for the MC33065
Thigh = +85°C for MC33065
4. This parameter is measured at the latch trip point with VFB = 0 V
5. Comparator gain is defined as AV
