FAN23SV15MAMPX

The FAN23SV15M is a highly efficient synchronous buck regulator. The regulator is capable Of operating With an hput range from 7 V to 18 V and supporting up to 15 A load currents. The device can operate from a 5 V rail if VIN, PVIN, and Pvcc are connected together to bypass the internal linear regulator. The FAN23SV15M 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) rntxie 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 deuce during fault conditions. After thermal shutdown is activated, a hysteresis feature restarts the deuce When normal operating temperature is reached.
