STMicroelectronics VIPER32DIP Integrated Off-line Switcher

The VIPER32DIP from STMicroelectronics is a high-performance, low-power off-line switched-mode power supply (SMPS) integrated circuit. It is designed to deliver a cost-effective and space-efficient power solution for a wide range of applications. The device incorporates a rugged vertical power MOSFET and a PWM controller in one package, providing an all-in-one solution for efficient power conversion.

This integrated circuit is particularly suitable for applications requiring a direct conversion from the AC mains to a regulated DC output, such as adapters, chargers, and standby power supplies. It can handle a wide input voltage range, making it versatile for global use. With its built-in protections, the VIPER32DIP ensures safe operation under various fault conditions, including overvoltage, overload, short-circuit, and thermal shutdown.

The VIPER32DIP features an 800V avalanche-rugged power section, which enhances the system's reliability and robustness by withstanding harsh line conditions and surges. The high voltage capability also reduces the stress on the components, extending the overall lifespan of the power supply. Additionally, the device offers low power consumption under no-load conditions, contributing to energy savings and compliance with green energy standards.

Its frequency jittering reduces electromagnetic interference (EMI), simplifying the design of low-noise power supplies. The fixed 60 kHz switching frequency ensures optimal balance between efficiency and component size, allowing designers to minimize the size of magnetic and filtering components.

The VIPER32DIP comes in a DIP-8 package, which is widely used and easy to integrate into various PCB layouts. Its lead-free and RoHS-compliant design also makes it an environmentally friendly choice for manufacturers looking to meet current and future green regulations.

In summary, the VIPER32DIP by STMicroelectronics is a highly-integrated, efficient, and reliable solution for designers looking to create compact, energy-efficient power supplies with minimal external components and simplified design processes.
