Zero-power standby SMPS with remote-control wake-up
Built around a VIPer0P 800 V avalanche-rugged high-voltage converter with zero-power standby, the STEVAL-ISA181V1 is a remote-controlled 12 V / 600 mA isolated flyback SMPS with a smart standby architecture featuring zero-power mode (ZPM). In ZPM idle state, power consumption is below 5 mW. The ZPM combined with the IR remote on/off control makes it ideal for air conditioning systems and power supplies that need to be remotely switched on/off during their working lifecycle. |
VIPer0P zero-power offline high-voltage converter
Introducing the VIPer0P high-voltage converter with jittered fixed-frequency current-mode PWM control for simplified EMI compliance and zero-power mode (ZPM) with an astounding < 4 mW (at 230 VAC) consumption. VIPer0P can enter and exit ZPM when the low voltage input/output pins (OFF or ON) are pulled to ground so a small and inexpensive safety extreme low voltage (SELV) switch can replace the bulky mains switch. The VIPer0P embeds a set of protections – including over-current protection (OCP), VCC clamp, maximum duty cycle and flux runaway – to enable a more robust and safer SMPS design.
The VIPer0p is ideal for all SMPS up to 7 W having a wide input voltage range including:
- Home appliances compliant with EuP Lot6 energy regulation
- Industrial equipment or digital consumer goods
Explore all the key benefits of the VIPer0P high-voltage converter with unique zero-power mode with the STEVAL-ISA174V1 non-isolated, flyback 6 W SMPS evaluation board.
