C2161PX2 Primary Sensing SMPS Controller

From initial application of power or from Run mode if VDD falls below VDDSLEEP 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.

C2161PX2 Features

* Advanced primary sensing controller achieves true CV/CC output characteristic without opto-coupler

* Full featured protection for over-temperature, input over-voltage, input under-voltage, output short-circuit

* Advanced PFM/PWM control and quasi-resonant switching for increased effic
