The FAN2306AMPX/ FAN2306MAMPX are highly efficient integrated synchronous buck regulators. 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 light-load efficiency by reducing switching frequency when the inductor is operating in Discontinuous Conduction Mode (DCM) at light loads. The FAN2306A includes an ultrasonic mode with minimum frequency clamp to keep the switching frequency above the audible range, while the FAN2306M does not include the minimum frequency clamp to maximize efficiency to extremely light loads.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.
