FAN2365AMPX: 10 A Synchronous Buck Regulator

Description: The FAN2365AMPX is a highly efficient synchronous ...
  • The FAN2365AMPX is a highly efficient synchronous buck regulator. The regulator is capable of operating with an input range from 4.5 V to 24 V and supporting up to 15 A continuous load currents.
    The FAN2365A utilizes Fairchild’s constant on-time control architecture to provide excellent transient response and to maintain a relatively constant switching frequency. This device utilizes Pulse Frequency Modulation (PFM) mode to maximize light-load efficiency by reducing switching frequency when the inductor is operating in discontinuous conduction mode at light loads, while clamping the minimum frequency above the audible range with ultrasonic mode.
    Switching frequency and over-current protection can be programmed to provide a flexible solution for various applications. Output over-voltage, under- voltage, over-current, and thermal shutdown protections help prevent damage to the device during fault conditions. After thermal shutdown is activated, a hysteresis feature restarts the device when normal operating temperature is reached.
