一,产品概述(General Description) dHM嘉泰姆
dHM嘉泰姆
The CXSD6260 is a 180 KHz fixed frequency PWM buck (step-down)dHM嘉泰姆
DC/DC converter,capable of driving a 5A load with high efficiency, low rippledHM嘉泰姆
and excellent line and load regulation. Requiring a minimum number of external components, the regulator is simple to use and include internal frequency dHM嘉泰姆
compensation and a fixed-frequency oscillator.dHM嘉泰姆
The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%.dHM嘉泰姆
An over current protection function is built inside.When short protection functiondHM嘉泰姆
happens, the operation frequency will be reduced from 180KHz to 48KHz. An internal compensation block is built in to minimize external component countdHM嘉泰姆

Pin NumberdHM嘉泰姆	Pin NamedHM嘉泰姆	DescriptiondHM嘉泰姆
1dHM嘉泰姆	GNDdHM嘉泰姆	Ground Pin. Care must be taken in layout. This pin should bedHM嘉泰姆 placed outside of the Schottky Diode to output capacitordHM嘉泰姆 ground path to prevent switching current spikes from inducingdHM嘉泰姆 voltage noise into CXSD6260.dHM嘉泰姆
2dHM嘉泰姆	FBdHM嘉泰姆	Feedback Pin (FB). Through an external resistor dividerdHM嘉泰姆 network, FB senses the output voltage and regulates it. ThedHM嘉泰姆 feedback threshold voltage is 1.25V.dHM嘉泰姆
3dHM嘉泰姆	SWdHM嘉泰姆	Power Switch Output Pin (SW). SW is the switch node thatdHM嘉泰姆 supplies power to the output.dHM嘉泰姆
4dHM嘉泰姆	VCdHM嘉泰姆	Internal Voltage Regulator Bypass Capacity. In typical systemdHM嘉泰姆 application, The VC pin connect a 1uf capacity to VIN.dHM嘉泰姆
5dHM嘉泰姆	VINdHM嘉泰姆	Supply Voltage Input Pin. CXSD6260 operates from a 8V to 36VdHM嘉泰姆 DC voltage. Bypass Vin to GND with a suitably largedHM嘉泰姆 capacitor to eliminate noise on the input.dHM嘉泰姆
