The VIPER0PHDTR chip from the Power Management IC (PMIC) family is an AC-DC converter and offline switcher that is used in embedded systems. It is a high performance solution that is capable of synchronizing with a variety of input voltages ranging from 12V to 18V. The chip includes a Pulse Width Modulator (PWM) controller, two synchronous power MOSFETs, and a high-side MOSFET driver with built-in overcurrent and temperature protection. With the VIPER0PHDTR, designers can quickly and easily implement high-efficiency, low-cost offline power systems.

The VIPER0PHDTR is designed to provide fast transient responses to sudden changes in the input voltage levels. It is able to sense the input voltage and supports load-line tracking and voltage feed-forward for even better transient response. The VIPER0PHDTR can also work in conditions where there is a large input voltage variation and deals with short-term voltage sags and overshoots.

The VIPER0PHDTR is designed to operate at very low switching frequencies, which helps to reduce the system noise. It is capable of a maximum switch frequency of 500kHz, which is up to five times faster than other offline switching solutions. This provides superior transient response and reduces the amount of heat generated in the power stages. This feature makes the VIPER0PHDTR an ideal choice for high-efficiency, low-cost offline power systems.

The VIPER0PHDTR also includes an over-current protection feature, which helps to protect the system from over-current conditions. The over-current protection is configurable and can be set to the desired threshold level. It also includes an adjustable current limit that allows the designer to adjust the current limit according to their system requirements.

The VIPER0PHDTR chip also includes a built-in over-temperature protection circuitry. This feature helps to protect the system from high temperatures that can be caused by excessive switching frequency. The over-temperature protection can be set to the desired threshold level to make sure that the system remains stable and operating at optimal levels even in the presence of unpredictable operating conditions.

In addition, the VIPER0PHDTR is designed to support a variety of output voltages, from 3.3V to 24V. The chip can be used to deliver single and multiple outputs, making it well-suited for a wide range of applications.

The VIPER0PHDTR is a great solution for high efficiency, low cost offline power systems. It provides fast transient responses to sudden changes in input voltage levels, and its over-current and over-temperature protection features make it suitable for use in a wide range of applications.
