The VIPER06LS from STMicroelectronics is a high-performance, low-power, off-line switched-mode power supply (SMPS) primary switcher. It is specifically designed to meet the needs of low-power applications, delivering a power capability of up to 5 watts in wide-range mains operation and up to 4 watts with a European voltage range. This makes the VIPER06LS an ideal choice for a wide range of domestic and industrial applications.
With an integrated 800V avalanche-rugged power MOSFET, the VIPER06LS offers enhanced robustness and reliability. The device operates in Pulse Frequency Modulation (PFM) at light load and features multiple protection features, including overload protection, overvoltage protection, and hysteresis thermal protection, ensuring safe operation under abnormal operating conditions.
The VIPER06LS is highly efficient, which is achieved through its ability to minimize power dissipation. It boasts a very low consumption under no-load condition, which makes it compliant with energy-saving regulations. Its built-in high-voltage startup circuitry ensures a rapid and efficient startup phase, further enhancing the device's performance.
Among its features, the VIPER06LS includes a jittered switching frequency, which reduces electromagnetic emissions, and an embedded error amplifier with a 1.2V reference. Its standby power consumption is less than 30mW at 265VAC, making it suitable for applications that require compliance with standby power regulations.
Intended for use in a variety of applications, the VIPER06LS is particularly well-suited for auxiliary power supplies, home appliances, power adapters, and other low-power utility devices. Its SO-8N and DIP-7 package options provide flexibility for different PCB layouts and space constraints.
Overall, the VIPER06LS is a testament to STMicroelectronics' commitment to providing energy-efficient and durable power solutions. Its combination of power efficiency, compact design, and protection features make it a reliable and cost-effective choice for designers looking to optimize their power supply systems.
