VIPER06HS is a dc-dc switching power conversion chip which can be applied in offline switched-mode power supply (SMPS). It is a component of the PMIC (Power Management Integrated Circuit) family of AC DC converters. It integrates an advanced micro-power embedded controller, power switch and synchronous rectifier, making it a reliable and cost-effective solution for off-line power supplies.

The VIPER06HS mainly comprises six external components: a transformer, an input/output capacitor, output inductor, current sensing resistor, diodes and a control IC (Viper06HS Driver Controller). The VIPER06HS is built on a highly reliable, voltage-mode controller platform, enabling it to accurately adjust the output voltage and current to a desired level.

The VIPER06HS also helps to reduce EMI and RFI generation. It ensures high performances at high frequency, with a switching frequency adjustable from 20kHz to 100kHz, through a single resistor. As a result, it provides optimal efficiency levels up to 95% in typical applications.

The VIPER06HS enables the user to meet predetermined ultra-low no-load standby power consumption requirements, without sacrificing output voltage and current accuracy. Advanced features such as User Programmable Under-Voltage Lockout (UVLO), Over Temperature protection (OTP) and Cycle-by-Cycle Over Current protection (OCP) keep the device safe from harm.

VIPER06HS is an efficient and reliable solution for today’s portable, distributed, low power and cost-sensitive applications, such as cell phones, cameras, notebook PCs, LCD TVs, game consoles and more.

To make sure the performance of the VIPER06HS is optimized to the highest standards, it offers a highly integrated, low-duty cycle average switching frequency and provides tight regulation, accurate current and voltage control, and fast current loop response. It is also equipped with a wide power range of 6 watt through to 60 watt, making it suitable for various electronic products.

In summary, the Viper06HS is an ideal choice for a wide range of AC/DC and DC/DC conversion applications. It provides a compact solution for small form factor, high power densities, low standby power, low EMI and high efficiency applications with a high degree of reliability.
