VIPer222 controller, supports up to 8W converter
It has an operating voltage range of 4.5V to 30V.


On the 6th, STMicroelectronics released the VIPer222 controller, which supports high-voltage converters up to 8W.

VIPer222 enables the implementation of various functions at a low cost while reducing the size of applications such as home appliances, building automation devices, smart lighting, and smart meters.

The new product integrates an error amplifier, a current sensing MOSFET, and a high-voltage startup circuit, making it suitable for use in various commonly used converter topologies. These include non-isolated flyback converters, isolated flyback converters that support primary or secondary regulation using optocouplers, buck converters, and buck-boost converters.

For the first time in ST’s highly integrated controller family, a power stage with 730V avalanche performance has been included. It provides short-circuit protection, thermal protection, pulse skipping protection, and soft-start functions, as well as circuitry that manages burst mode operation to improve efficiency under light loads.

It has an operating voltage (VCC) range of 4.5V to 30V, so it can easily supply power to the device regardless of the desired output voltage. With a low starting voltage of 30V DC, it allows for a wide input voltage range and enables easy starting with a low supply voltage. It complies with eco-friendly guidelines with power consumption of less than 40mW under light load, and features a jitter-supported PWM controller that allows the use of small filter components.

The VIPer222 is currently in production and is supplied in a 5mm × 4mm SSOP10 package. The price starts at $0.33 for a purchase of 1,000 units.
