FAN2315AMPX Information

FAN23A Synchronous Buck Regulators

ON Semiconductor FAN23A High-Efficiency Synchronous Buck Regulators operate with a 4.5-24V input range, support up to 24A continuous load currents, and offer an efficiency rating over 96%. Designed using Fairchild's constant on-time control architecture, the FAN23A regulators offer excellent transient response. This architecture also maintains a relatively constant switching frequency of 200kHz to 1.5MHz. Designers can use the Pulse Frequency Modulation (PFM) mode to maximize load efficiency. This capability is beneficial when the inductor operates in the discontinuous conduction mode with light loads. Undervoltage, output overvoltage, overcurrent, and thermal shutdown protections help prevent damage to the FAN23A regulators during fault conditions. In the event of a thermal shutdown, a hysteresis feature restarts the regulator when the normal operating temperature is reached. Designers can program the frequency as well as the overcurrent protection to meet the specific application requirements. Typical applications include notebooks, servers and desktop computers, game consoles, telecommunications, storage, and base stations.Learn More
