Overview
CS5422 Dual Out−of−Phase Synchronous Buck Controller with Current Limit The CS5422 is a dual N−channel synchronous buck regulator controller.
It contains all the circuitry required for two independent buck regulators and utilizes the V2™ control method to achieve the fastest possible transient response and best overall regulation, while using the least number of external components.
The CS5422 features out−of−phase synchronization between the channels, reducing the input filter requirement.
The CS5422 also provides undervoltage lockout, Soft Start, built in adaptive FET non−overlap and hiccup mode overcurrent protection.
The part is available in a 16 Lead SO Narrow or 24 Lead Fused SO Wide package allowing the designer to minimize solution size.
Features • V2 Control Topology • Hiccup Mode Overcurrent Protection • 150 ns Transient Response • Programmable Soft Start • 100% Duty Cycle for Enhanced Transient Response • 150 kHz to 600 kHz Programmable Frequency Operation • Switching Frequ...
