The FAN23SV65MPX is a highly efficient integrated synchronous Buck Regulator capable of operating with an input range from 7 to 24V and supporting up to 15A continuous load current. The device can operate from a 5V rail (±10%) if VIN, PVIN and PVCC are connected together to bypass the internal linear regulator. The FAN23SV65 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 overcurrent protection can be programmed to provide a flexible solution for various applications.
