» Product Change Notification |
The FAN23SV56AMPX is a highly efficient integrated 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.
The FAN23SV56 utilizes ON Semiconductor’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.
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. A hysteresis feature restarts the device when normal operating temperature is reached.
