Maximum package power dissipation limits must be observed. 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: 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 = ΔV Compensation ΔV Current Sense |
