Pin No Pin Name Function 1 LATCH Latch−Off Input 2 FB 3 CS Feedback Current Sense 4 GND 5 DRV 6 VCC Drive output VCC input 8 HV High−voltage pin Pin Description Pull the pin up or down to latch−off the controller. An internal current source allows the direct connection of an NTC for over temperature detection An optocoupler collector to ground con.
a timer−based fault detection that ensures the detection of
overload independently of an auxiliary winding, and an adjustable compensation to help keep the maximum power independent of the input voltage.
Finally, due to a careful design, the precision of critical parameters is well controlled over the entire temperature range (−40°C to +125°C).
