Power management integrated circuits (PMICs) are key devices in most modern electronic systems, and the VIPER28LD is an example of a high-performance PMIC. This PMIC is part of a highly integrated family of Voltage Controlled AC and DC (VACDC) converters, offline switchers, and pulse width modulators (PWMs) for use in a wide range of applications.

The VIPER28LD is a highly integrated PMIC that combines four voltage regulators (VR), four power MOSFET drivers (MOST), and one PWM, in one small package. Each voltage regulator and power MOSFET driver has an on-board power supply and separate operating voltages, making it suitable for multi-voltage applications. Additionally, the VR and MOST have individually adjustable output voltages, allowing further optimization of the design.

The VIPER28LD is designed for use in applications such as AC-DC power supplies, DC-DC converters, and motor drives. It supports a wide range of input voltages and frequencies, allowing it to be used in both mains power and low voltage applications. Additionally, the VIPER28LD contains several protection features, such as over-temperature protection, current limit and short circuit protection, making it suitable for use in a wide variety of operating environments.

The VIPER28LD’s versatility and high-performance make it an ideal solution for all types of AC-DC and DC-DC conversion, as well as motor control applications. It is designed to provide precise control over the output voltage, current, and frequency, making it suitable for a variety of applications such as computers, communications equipment, consumer electronics, and audio and video products.

The VIPER28LD is powered by an embedded voltage control oscillator (VCO), which is used to generate a constant voltage output and a variable frequency output. The VCO also controls the current limit of the output, providing better protection against short-circuiting. Additionally, the VIPER28LD includes a number of programmable features, such as over-temperature protection and power saving modes.

The VIPER28LD is also designed for use in offline switchers, where it provides precise control of the output voltage and frequency. The VIPER28LD can be used in a variety of topologies, including buck, boost, flyback, and forward converters. It is also applicable to buck-boost topologies, allowing it to be used as a low-cost solution for high voltage applications.

The VIPER28LD is designed to be used in Pulse Width Modulation (PWM) applications, where it can be used to control the speed of a motor. By using the adjustable frequency feature of the VIPER28LD, the motor speed can be varied depending on the application. Additionally, the VIPER28LD includes built-in safety features, such as over-temperature protection and current limit protection, making it suitable for use in a wide variety of applications.

In summary, the VIPER28LD is a high performance, highly integrated PMIC for AC-DC and DC-DC conversion, offline switchers and Pulse Width Modulation applications. Its small size and wide range of features make it suitable for a variety of applications, such as computers, communications equipment, consumer electronics, and audio and video products. Additionally, its over-temperature protection, current limit and short circuit protection offer improved safety in a wide range of operating environments.
