STMicroelectronics VIPER53DIP-E - Off-Line SMPS Primary Switcher

The VIPER53DIP-E from STMicroelectronics is a robust and versatile off-line switched-mode power supply (SMPS) primary switcher IC, designed to deliver a reliable and efficient solution for a wide range of power supply applications. It is housed in a DIP-16 package, offering a compact footprint for space-constrained applications.

This high-performance device integrates a PWM controller and a 500V vertical power MOSFET, allowing for the creation of a cost-effective power supply with a minimal external component count. The VIPER53DIP-E is well-suited for applications requiring a power range up to several tens of watts, making it an ideal choice for adapters, chargers, and auxiliary supplies.

One of the key features of the VIPER53DIP-E is its built-in protection circuitry. It offers overvoltage protection (OVP), overload protection (OLP), and hysteretic thermal shutdown to ensure the safety and longevity of the power supply and the end application. These protections are essential for maintaining performance and reliability under various operating conditions.

The device operates at a fixed 60 kHz frequency with frequency jittering, which helps to reduce electromagnetic interference (EMI), thereby simplifying the design of the EMI filter and helping to comply with the most stringent regulations. Additionally, the VIPER53DIP-E supports burst mode operation, which significantly improves efficiency at light load and reduces standby power consumption, making it suitable for energy-saving applications.

With its built-in soft-start feature, the VIPER53DIP-E minimizes the stress on the components during startup, extending the life of the product. The IC also includes an error amplifier and an adjustable output voltage, enabling precise regulation for a stable power supply.

In summary, the VIPER53DIP-E from STMicroelectronics is a high-performance, feature-rich primary switcher IC that offers an efficient and protected solution for off-line power supplies. Its comprehensive set of features, combined with its compact DIP-16 package, make it a highly attractive option for designers looking to create cost-effective and reliable power solutions.
