Power Management IC (PMIC) devices are electronic components that enable manufacturers to deliver current from a power supply to their products quickly and efficiently. AC-DC converters, offline switchers, and VIPER20-22-E are all PMIC components. The VIPER20-22-E is a high-performance single-channel, offline switcher that features minimal power dissipation and a high degree of EMI performance. It is a popular choice for applications in a range of portable or fixed devices that require a reliable, cost-efficient and high-efficiency power delivery solution.

The VIPER20-22-E is designed to provide power conversion and regulation for portable or fixed applications that use 3 V to 12 V input voltage, while delivering continuous output current up to 750 mA. Internally, the VIPER20-22-E has three basic parts: a power stage, an integrated control circuit and protection circuitry. The power stage consists of one MOSFET, which is used to switch the power supply and regulate output voltage. The control circuitry provides target voltage regulation, synchronization, current-limit protection and frequency jittering, while the protection circuitry provides reverse-protection, as well as a range of other safety features.

In operation, the VIPER20-22-E is quite simple. When the input voltage rises above a preset minimum of 3 V, the power stage begins to switch, which causes the output voltage to rise. The control circuitry senses the output voltage and compares it to the target value. When the output voltage reaches the target, the control circuitry reduces the switching frequency until the output reaches the set target. A current-limit circuit is also included to protect the system in the event of an overload or short circuit.

The VIPER20-22-E is well-suited for applications that require efficiency and protection. It provides a very high level of efficiency, with typical efficiency ratings of better than 90%. It is also very reliable, with a lifecycle of more than 10 million operations. Finally, it is very safe, with reverse-voltage protection, short circuit protection and over-temperature protection.

The VIPER20-22-E is a popular choice for powering a range of portable or fixed applications. It is used for powering smartphones, tablets, home appliances, embedded systems and embedded LED lighting. It is also used to power various automotive systems, including infotainment systems, cluster displays, body control modules and active air suspensions, just to name a few. The VIPER20-22-E is a great choice for any application that requires high power, efficiency and reliable performance.
