The VIPER100 (022Y) is a member of the advanced NCP565/567/571 family of pulse width modulation (PWM) controllers for synchronous Buck and Buck-Boost application. It offers low quiescent current, high accuracy, and fast line and load transient responses.

The VIPER100 (022Y) is a state-of-the-art device for the cost-effective implementation of low-density low-power Buck and Buck-Boost converters in space-constrained applications. The device combines reliable protection features with low standby current, fast response and excellent regulation accuracy as well as higher integration levels in a small 8-pin SOIC package. It can also easily implement full-bridge architectures.

The VIPER100 (022Y) is designed to support a wide range of solutions, including direct offline AC/DC converters for off-line applications, as well as LED drivers, motor drives and other DC/DC converter architectures. It supports both buck and buck-boost converters with constant-on-time PWM control scheme and can handle up to 100kHz switching frequency. The device\'s PWM control scheme provides flexibility and accuracy resulting in very low output ripple voltage and high efficiency, while its tight regulation of output voltage guarantees reliable operation of end equipment.

The VIPER100 (022Y) is ideally suited to drive synchronous or diode-rectifier buck, or buck-boost converter topologies. Its current mode control architecture automatically adjusts the PWM duty cycle in response to load variations or changes to input/output voltages. This allows the device to reach equilibrium quickly, meaning that the designer can expect fast transient response to changes in load and line conditions.

The VIPER100 (022Y) is a secure device that includes the integration of various protection features such as soft start, over-current protection, frequency jittering and over-temperature protection. Its Over-Current Protection (OCP) is fully programmable and offers excellent protection with minimal system overhead.

In addition, the VIPER100 (022Y) is also capable of handling high input voltage, ranging from 4.5V to 55V, and can be used for wide input-range applications such as communication networks and industrial systems.

Overall, the VIPER100 (022Y) is a great choice for designing power management systems requiring fast transient response and high efficiency, such as medical devices, industrial systems, telecommunication equipment, automotive applications and versatile consumer electronics.
