This SMPS system features an isolated flyback converter based on VIPer0P and special STM32 core logic to manage the VIPer0P for extremely low power consumption during ZPM while supplying the microcontroller and IR receiver and still maintaining relatively high overall efficiency during normal operation. The IR remote interface consists of a dedicated IR TX board and very low consumption TIA / band pass filter RX.
In the ZPM idle state, the device is shut down fully and the residual consumption from the 230VAC mains is below 5 mW. The IC enters ZPM by pulling the OFF pin to SGND for more than 10 ms and exits ZPM (resuming normal switching) by pulling the ON pin to SGND for more than 20 μs.
This function can be tested by acting on the tactile switches connected to the ON and OFF pins.
The proposed power supply is set in isolated flyback topology with 12 V output voltage and 7.2 W nameplate power.
