They are capable of operating with an input range from 4.5 V to 18 V, supporting 6 A continuous load currents. These devices utilize Fairchild’s constant on-time control architecture to provide excellent transient response and to maintain a relatively constant switching frequency. The FAN2306A / FAN2306MA utilize Pulse Frequency Modulation (PFM) mode to maximize lightload efficiency by reducing switching frequency when the inductor is operating in Discontinuous Conduction Mode (DCM) at light ...
