C2161PX2 - Primary Sensing SMPS Controller
From initial application of power or from Run mode if VDD falls below ïVDDSLEEP below VDDREG, the controller changes to Sleep mode.
Non-essential controller circuits are powered down and the external switching transistor (Q1) is held off.
Exit from Sleep mode occurs when VDD rises above VDDRUN and t
