PMIC - AC DC Converters, Offline Switchers

The VIPER25HD application field and working principle are widely used in the power management integrated circuits (PMIC) industry. As part of PMIC, the VIPER25HD application field focuses on AC-DC converters, offline switchers, as well as adaptive bypass and load modulation. The VIPER25HD is a high-performance, highly integrated monolithic DC/DC converter that uses a quasi-resonant flyback topology. It is designed for low-power tasks, such as DSSS receivers, remote controls, and USB chargers. The VIPER25HD requires only a few external components to configure and supports a wide input voltage range from 2.5V to 7V. The VIPER25HD works by transferring energy from primary side to secondary side of the converter through a transformer core. The switching is controlled by a Pulse Width Modulation (PWM) circuit. The converter can achieve high efficiencies of up to 96% in the typical power delivery range of 4W.The VIPER25HD features high-speed response, simple regulation, low output ripple and low noise, low EMI and low power consumption. In addition, it has built-in over temperature protection and under voltage lockout. The VIPER25HD also incorporates a soft start time limitation circuit to prevent overloading. The VIPER25HD is suitable for a variety of applications, including distributed power, adaptive bypass and load modulation, battery powered systems, and isolated supplies. It can be used for applications such as medical devices, LCD TV, set-top boxes and gaming consoles. The VIPER25HD can also be used to control and regulate the output voltage from a DC-DC converter. The output voltage of the converter can be adjusted by changing the duty cycle of the Pulse Width Modulation (PWM) circuit. This can be used to regulate the voltage to the load without the need for an external voltage regulator.In conclusion, the VIPER25HD is an optimal choice for applications requiring an integrated DC/DC converter that offers high-performance and low power consumption. It is particularly suitable for low-power tasks such as DSSS receivers, remote controls, and USB chargers. Its wide input voltage range, advanced features and high efficiency make it an ideal choice for applications that require high performance and low power.
