Description

STMicroelectronics VIPER25HN High-Voltage Converter

The VIPER25HN is a cutting-edge high-voltage converter integrated circuit (IC) from STMicroelectronics, designed to deliver exceptional performance and reliability for a wide range of power supply applications. This IC is part of the VIPerPlus family, which is known for its energy-efficient solutions and robust design, making it an ideal choice for designers looking to create compact, high-performance power supplies with minimal external components.

At the heart of the VIPER25HN is an 800V avalanche-rugged power section, a PWM operation at 60 kHz with a frequency jittering feature for lower EMI, and multiple protection features that enhance the overall system reliability. The high-voltage capability ensures that the device can withstand power surges and enables the direct connection to the rectified mains, thereby eliminating the need for a power transformer in many applications.

This IC is particularly suitable for applications that require a flyback, buck, or buck-boost converter topology. With its integrated high-voltage startup and sense-FET, the VIPER25HN provides an efficient solution for offline power supplies capable of delivering up to 5W in wide range mains conditions and up to 12W with a typical European voltage range. This makes it a versatile choice for designers working on auxiliary power supplies for home appliances, industrial control systems, and standby power supplies for TVs and monitors.

Protection features of the VIPER25HN include overvoltage protection (OVP), overload protection (OLP), hysteretic thermal shutdown, and overcurrent protection (OCP), which safeguard the IC and the power supply from various fault conditions. The built-in soft-start functionality ensures a controlled startup and helps to prevent inrush current-related issues.

For ease of use, the VIPER25HN is available in a compact DIP-7 or SSO-10 package, allowing for flexible PCB design and space-saving layouts. The device's robustness, combined with STMicroelectronics' commitment to quality, ensures that the VIPER25HN is a reliable choice for powering today's sophisticated electronic systems.

Overall, the VIPER25HN from STMicroelectronics stands out as a high-performance, energy-efficient solution for a variety of power conversion applications, providing designers with a flexible and dependable integrated circuit that meets the stringent demands of modern electronics.
