STEVAL-ISA181V1
12 V / 600 mA high voltage flyback converter with remote
standby control using the VIPer0P
Data brief
Features
 Smart standby architecture using Zero
Power Mode (ZPM) with IR remote on/off
control suitable for Air Conditioning
subsystems and other applications
 Based on VIPer0P high voltage converter
with embedded 800V avalanche rugged
power MOSEFET and a current mode PWM
controller with a set of protections for
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
 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
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.
