S T E VA L - I S A 1 8 1 V 1 12 V / 600 mA high voltage flyback converter with remote standby control using the VIPer0P Data brief Meets IEC61000-4-2(ESD), IEC61000-4-4 (EFT) and IEC61000-4-5 (Surge) RoHS compliant Description 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 230V mains is below 5 mW. The IC enters ZPM AC by pulling the OFF pin to SGND for more than 10 Features ms and exits ZPM (resuming normal switching) by pulling the ON pin to SGND for more than 20 Smart standby architecture using Zero s. Power Mode (ZPM) with IR remote on/off control suitable for Air Conditioning This function can be tested by acting on the subsystems and other applications tactile switches connected to the ON and OFF Based on VIPer0P high voltage converter pins. with embedded 800V avalanche rugged The proposed power supply is set in isolated power MOSEFET and a current mode PWM flyback topology with 12 V output voltage and 7.2 controller with a set of protections for W nameplate power. enhanced system reliability Input power consumption in Zero Power Mode lower than 8 mW at 230VAC (switched- off by remote IR control) while supplying microcontroller and IR receiver Input power consumption at no load less than 30 mW at 230VAC, including microcontroller consumption Average efficiency > 80.2% compliant with EuCoC rev. 5 Tier 2 and EPS of DOE USA Meets IEC55022 Class B conducted EMI even with reduced EMI filter, thanks to the frequency jittering feature November 2016 DocID030054 Rev 1 1/6 www.st.com For further information contact your local STMicroelectronics sales office Specifications STEVAL-ISA181V1 1 Specifications Topology: flyback Isolation: yes Input power consumption: Less than 8 mW at 230 VAC in Zero-Power Mode Less than 30 mW at 230 V in no-load condition AC compliant with EuCoC rev. 5 Tier 2 and EPS of DOE USA input voltage: 85 V AC - 265 VAC Output voltage: 12 V, 600 mA Converter frequency: 120 kHz with jittering Max ambient temperature: 60 C Automatic restart protections: OLP, VCC clamp, max duty cycle counter, thermal shutdown Pulse-skip protection to prevent the flux-runaway SMPS board dimensions: 68 mm x 36 mm IR TX control board: 28 mm x 25 mm 2/6 DocID030054 Rev 1
