Key Featrues
Prebias Startup/Monotonic: Ensures a smooth and controlled startup even when the output voltage is precharged, preventing voltage overshoots or instability. This feature is critical for applications requiring reliable power-up sequences, such as servers and telecom equipment.
1% Output Accuracy: Provides highly precise output voltage regulation, enhancing system reliability and performance. This level of accuracy is particularly beneficial for sensitive electronics in wireless base stations and storage systems.
Adjustable Frequency (200kHz to 1MHz): Allows users to optimize the switching frequency for specific applications, balancing efficiency and noise performance. This flexibility is ideal for noise-sensitive environments like networking and telecom.
Lossless, Foldback Current Limit: Protects the system from overcurrent conditions while minimizing power dissipation during faults. This feature improves efficiency and safety in high-current applications like servers and storage systems.
Overvoltage Protection (OVP): Safeguards the system against voltage spikes, ensuring long-term reliability and preventing damage to downstream components. This is especially important in industrial and telecom environments with fluctuating power conditions.
