NX9548 Datasheet PDF - Microsemi

The NX9548 is a synchronous buck switching regulator with 21mohm internal N-channel MOSFETs, primarily intended for portable (mobile) applications.  It is optimized to convert bus voltages as high as 24V down to as low as 0.75V, with output currents as high as 9A.  It can be selected to operate in synchronous mode or non-synchronous (diode emulation) mode at light loads, to improve. Adaptive constant on time (COT) control provides extremely fast transient response to line and load steps, while at the same time providing near-constant switching frequency over a wide input voltage range.  The frequency is adjustable too. The NX9548 features overcurrent protection (OCP), feedback undervoltage lockout (FB UVLO), and overvoltage protection (OVP).  It also includes an integrated bootstrap Schottky diode, and provides low-voltage (5V) gate-drive capability.  In addition it provides a Power Good indicator and has adaptive deadtime.
