Fairchild Semiconductor FAN23SV56AMPX
The FAN23SV56A is a highly efficient synchronous buck regulator. The regulator is capable of operating with an input range from 7 V to 24 V and supporting 6 A continuous load currents. The device can operate from a 5 V rail (±10%) if VIN, PVIN, and PVCC are connected together to bypass the internal linear regulator.| Part No. | FAN23SV56AMPX |

DESCRIPTION
The FAN23SV56A utilizes Fairchild’s constant on-time control architecture to provide excellent transient response and maintain a relatively constant switching frequency. Pulse Frequency Modulation (PFM) Mode maximizes light-load efficiency by reducing switching frequency when the inductor is operating in Discontinuous Conduction Mode (DCM) at light loads, while clamping the minimum frequency above the audible range with Ultrasonic Mode.
