Secondary Side SMPS ECO

Mode Controller for Low

Standby Power

The NCP4352 is a secondary side SMPS controller designed for use

in applications which require extremely low consumption. The device

is capable of detecting “light load” conditions and entering the power

supply into low consumption “ECO mode”.

During ECO mode, the output voltage decreases to an adjustable

level, allowing higher efficiency for light load condition while

keeping lower but regulated voltage supply. Once more energy is

required, the NCP4352 automatically switches back to the normal

mode regulation of output voltage.

During normal power supply operation, the NCP4352 provides

integrated voltage and current feedback regulation, replacing the need

for a shunt regulator. Feedback control is provided through

optocoupler to primary side SMPS controller.
