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 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 controls the output regulat.
increases safety level of the final application.
Finally, due to a careful design, the precision of critical parameters is well controlled over the entire temperature range (−40°C to +125°C).
