NCP4355  
Secondary Side SMPS OFF  
Mode Controller for Low  
Standby Power  
Description  
http://onsemi.com  
The NCP4355 is a secondary side SMPS controller designed for use  
in applications which require extremely low no load power  
consumption. The device is capable of detecting “no load” conditions  
and entering the power supply into a low consumption OFF mode.  
During OFF mode, the primary side controller is turned off and energy  
is provided by the output capacitors thus eliminating the power  
consumption required to maintain regulation. During OFF mode, the  
output voltage relaxes and is allowed to decrease to an adjustable  
level. Once more energy is required, the NCP4355 automatically  
restarts the primary side controller by ONOFF current that flows  
through ONOFF optocoupler. The NCP4355 controls the primary  
controller with an “Active ON” signal, meaning that it only drives  
optocoupler current during ON mode to minimize consumption during  
OFF mode.

During normal power supply operation, the NCP4355 provides  
integrated voltage feedback regulation, replacing the need for a shunt  
regulator. The A and C versions include a current regulation loop in  
addition to voltage regulation.  
The NCP4355 includes a LED driver pin (except C version)  
implemented with an open drain MOSFET driven by a 1 kHz square  
wave with a 12.5% duty cycle for indication purpose.
