Product Description

The FAN23SV70AMX 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 up to 20 A load currents. The device can operate from a 5 V rail (±10%) if V are connected together to bypass the internal linear regulator.The FAN23SV70A utilizes Fairchild’s constant on-time control architecture to provide excellent transient response and to maintain a relatively constant switching frequency. The 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.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.
