STMicroelectronics High Voltage Switcher 650 mA 11W Surface Mount 10-Pin SSOP VIPER222LSTR

The STMicroelectronics VIPER222LSTR is a high-performance, high-voltage switcher designed for power management IC applications. It integrates a rugged 730 V power MOSFET with PWM control in a compact 10-pin SSOP surface mounting package. This device is suited for efficient AC-DC conversion in industrial, laboratory, and commercial electronics requiring reliable voltage switching and conversion.

The converter features an embedded high-voltage start-up and current sense circuit, reducing the need for additional external components and thus lowering the Bill of Materials (BoM). Using frequency jittering, the device spreads EMI, allowing the reduction in size of EMI filtering components.

Its burst mode operation helps maintain very low input power consumption when operating under light load conditions, contributing to energy-efficient designs. Built-in short-circuit protection and thermal shutdown ensure robust operation and safeguard against abnormal conditions.

The device supports a flyback topology with a maximum duty cycle of 80%, enabling effective energy delivery at output powers up to 11 W and maximum output current of 650 mA. It operates across an extended temperature range from -40°C to +150°C, suitable for diverse industrial environments.

The VIPER222LSTR is RoHS compliant, affirming compliance with environmental safety standards. Its compact footprint of 6.2 mm width and 5 mm length and height aids integration into space-constrained PCB layouts.

This power management IC is ideal for applications in industrial machines, consumer electronics, and embedded power supply solutions where efficient AC-DC conversion is critical. Its rugged design and integrated protection features provide reliability for long-term usage.
