With robust, advanced high-voltage converters, power factor correctors, a variety of controllers and supervisors/housekeeping ICs, together with innovative architectures and extended temperature ranges, ST can offer integrated solutions and meet all switching-mode power supply design needs.
New generation AC-DC converters reduce power consumption and increase efficiency, essential for powering the majority of mains equipment. When combined together, ST power factor correctors, PWM controllers and offline converters significantly lower system power consumption to outperform the most demanding energy-saving regulations, such as 80 PLUS® Initiative, ErP Lot 6, Energy Star, and many others.
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
