STEVAL-ISA099V1 - STMicroelectronics Product Overview

The STEVAL-ISA099V1 from STMicroelectronics is a highly integrated and efficient power management solution designed for a wide range of applications. This compact evaluation board is based on the VIPer0P high-voltage converter, which integrates a PWM controller and a 700V rugged power MOSFET, making it an excellent choice for power supply units requiring a low power consumption in standby mode.

With its smart power-saving features, the STEVAL-ISA099V1 is specifically tailored for applications that demand high energy efficiency and minimal standby power consumption. It is well-suited for household appliances, office equipment, power adapters, and smart meters, among others. The board operates over a wide input voltage range, making it versatile for use in various global markets and power conditions.

The evaluation board showcases the capabilities of the VIPer0P, including its ability to maintain high efficiency at different load conditions. It also demonstrates the device's brown-out protection feature, which safeguards the power supply during low input voltage conditions. The VIPer0P's jittered switching frequency reduces electromagnetic interference (EMI), enhancing the performance of the end application in terms of noise immunity.

Key features of the STEVAL-ISA099V1 include:

• Integrated 800V avalanche-rugged power MOSFET
• Fixed 60 kHz switching frequency with frequency jittering for lower EMI
• Standby power < 30 mW at 265 VAC
• Limiting current with adjustable set point
• Multiple protections: thermal shutdown, overcurrent, and overvoltage

The board is designed for ease of use, with a minimal number of external components required to complete the power supply design. This simplifies the development process and accelerates time-to-market for designers and engineers.

By utilizing the STEVAL-ISA099V1 evaluation board, developers can quickly assess the performance of the VIPer0P and implement a highly efficient power solution in their designs. The board's robust feature set and flexible design make it an invaluable tool for developing power-efficient applications.
