This integrated circuit can be damaged by ESD. Orister Corporation recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

DESCRIPTION
Ground.
Totem output to drive the external Power MOSFET.
Current sense input.
The voltage feedback from auxiliary winding. Connected to resistor divider from auxiliary
winding reflecting output voltage. PWM duty cycle is determined by EA output and
current sense signal at pin 4.
Loop Compensation for CV Stability.
Power Supply.
