STEVAL-ISA181V1

评估板, 12V / 600mA 高电压反激转换器, 远程独立控制

The from STMicroelectronics is a 12V/600mA high voltage flyback converter with remote standby control using the VIPer0P. 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 device shut down fully and the residual consumption from the 230VAC mains is below 5mW. The IC enters ZPM by pulling the OFF pin to SGND for more than 10ms and exits ZPM resuming normal switching by pulling the ON pin to SGND for more than 20µs. This function can be tested by acting on the tactile switches connected to the ON and OFF pins.
