一, 产品概述(General Description) aYc嘉泰姆
aYc嘉泰姆
The CXSD62232 is a monolithic synchronous buck regulator. The device integrates two 90mΩ MOSFETs, and provides2.2A of continuous loadcurrent over a wide input voltage of 4.75V aYc嘉泰姆
to 37V.Current mode control provides fast transient response and cycle-by-cycle current limit.An adjustable soft-start prevents inrush current at turn-on, and inshuJTMTown mode aYc嘉泰姆
the supply current drops to 1μA.This device, available in an SOP8-PP package, provides a verycompact solution with minimal external componentsaYc嘉泰姆

Pin NumberaYc嘉泰姆	Pin NameaYc嘉泰姆	DescriptionaYc嘉泰姆
1aYc嘉泰姆	BSaYc嘉泰姆	High-Side Gate Drive Boost Input. BS supplies the drive for the high-side N-ChannelaYc嘉泰姆 MOSFET switch. Connect a 0.01μF or greater capacitor from SW to BS to power theaYc嘉泰姆 high side switch.aYc嘉泰姆
2aYc嘉泰姆	INaYc嘉泰姆	Power Input. IN supplies the power to the IC, as well as the step-down converteraYc嘉泰姆 switches. Drive IN with a 4.75V to 32V power source. Bypass IN to GND with aaYc嘉泰姆 suitably large capacitor to eliminate noise on the input to the IC. See Input Capacitor.aYc嘉泰姆
3aYc嘉泰姆	SWaYc嘉泰姆	Power Switching Output. SW is the switching node that supplies power to the output.aYc嘉泰姆 Connect the output LC filter from SW to the output load. Note that a capacitor isaYc嘉泰姆 required from SW to BS to power the high-side switch.aYc嘉泰姆
4aYc嘉泰姆	GNDaYc嘉泰姆	Ground.aYc嘉泰姆
5aYc嘉泰姆	FBaYc嘉泰姆	Feedback Input. FB senses the output voltage to regulate that voltage. Drive FBaYc嘉泰姆 with a resistive voltage divider from the output voltage. The feedback thresholdaYc嘉泰姆 is 0.923V. See Setting the Output Voltage.aYc嘉泰姆
6aYc嘉泰姆	COMPaYc嘉泰姆	Compensation Node. COMP is used to compensate the regulation control loop.aYc嘉泰姆 Connect a series RC network from COMP to GND to compensate the regulationaYc嘉泰姆 control loop. In some cases, an additional capacitor from COMP to GND isaYc嘉泰姆 required. See Compensation Components.aYc嘉泰姆
7aYc嘉泰姆	ENaYc嘉泰姆	Enable Input. EN is a digital input that turns the regulator on or off. Drive EN high toaYc嘉泰姆 turn on the regulator, drive it low to turn it off. Pull up with 100kΩ resistor foraYc嘉泰姆 automatic startup.aYc嘉泰姆
8aYc嘉泰姆	SSaYc嘉泰姆	Soft-Start Control Input. SS controls the soft start period. Connect a capacitor from SSaYc嘉泰姆 to GND to set the soft-start period. A 0.1μF capacitor sets the soft-start period to 15ms.aYc嘉泰姆 To disable the soft-start feature, leave SS unconnected.aYc嘉泰姆
