EM8822A - Single stage Buck/Buck-Boost PFC Controller
EM8822A is a voltage mode Buck/Buck-boost PFC controller operating at transition mode.
It keeps the Buck / Buck-boost converter in constant on time operation to achieve high power factor.
This device provides protections of internal soft start, over voltage protection, over current protection and th
