Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. This device series contains ESD protection and exceeds the following tests: Human Body Model 4000 V per Mil−Std−883, Method 3015.
Charged Device Model 2000 V per JEDEC Standard JESD22−C101D
2. This device contains latchup protection and exceeds 100 mA per JEDEC Standard JESD78.
ELECTRICAL CHARACTERISTICS (Unless otherwise noted: For typical values TJ = 25°C, VCC = 12 V, VZCD = 0 V, VFB = 3 V,
VCS = 0 V, Vfault = 1.5 V, CT = 680 pF) For min/max values TJ = −40°C to +125°C, Max TJ = 150°C, VCC = 12 V)

3. Guaranteed by design.
4. The peak current setpoint goes down as the load decreases. It is frozen below Ipeak(VCO) (Ipeak = cst)
5. If negative voltage in excess to −300 mV is applied to ZCD pin, the current setpoint decrease is no longer guaranteed to be linear
6. Minimum value for TJ = 125°C
7. NTC with R110 = 8.8 kW.
