Microchip NX9548ILQ-TR

Manufacturer No:

NX9548ILQ-TR

Manufacturer:

Microchip

Package:

32-VFQFN Exposed Pad

Description:

The NX9548 is a synchronous buck switching regulator with 21 mΩ internal N-channel MOSFETs, primarily intended for portable (mobile) applications. The NX9548 operates from 4.5 V to 24 V, and the output voltage range is from 0.75 V to 5 V, with output currents as high as 8 A. It can be selected to operate in synchronous mode, or non-synchronous (diode emulation or PSM) mode at light loads, to improve efficiency. 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 also externally adjustable. The NX9548 features overcurrent protection (OCP), feedback under-voltage lockout (FB UVLO), and overvoltage protection (OVP). It also includes an integrated bootstrap Schottky diode, and provides lowvoltage (5 V) gate-drive capability. In addition it provides a Power Good indicator and has adaptive dead time.
