The FAN23SV06AMPX/FAN23SV06PAMPX is a highly efficient integrated synchronous buck regulator. The regulator is capable of operating with an input range from 7 V to 18 V and supporting 6 A continuous load currents. The device can operate from a 5 V rail (±10%) if V are connected together to bypass the internal linear regulator.These devices utilize Fairchild’s constant on-time control architecture to provide excellent transient response and to maintain a relatively constant switching frequency. The FAN23SV06A 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. The FAN23SV06PA with forced Pulse Width Modulation (PWM) mode is available for applications that require a relatively constant switching frequency across the full load range. 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.
