40V nominal isolated output. The output power is 500mW.
The HV9606 current-mode PWM controller features a built-in start-up regulator that can be used to operate the IC
from inputs of 15V to 250V. Other features include built-in soft start, programmable input under voltage lockout and
hysteresis, and standby current of 6碌A(chǔ) (below UVLO).
