一,产品概述(General Description) 2CR嘉泰姆
2CR嘉泰姆
The CXSD6260 is a 180 KHz fixed frequency PWM buck (step-down)2CR嘉泰姆
DC/DC converter,capable of driving a 5A load with high efficiency, low ripple2CR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 2CR嘉泰姆
compensation and a fixed-frequency oscillator.2CR嘉泰姆
The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%.2CR嘉泰姆
An over current protection function is built inside.When short protection function2CR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 count2CR嘉泰姆

Pin Number2CR嘉泰姆	Pin Name2CR嘉泰姆	Description2CR嘉泰姆
12CR嘉泰姆	GND2CR嘉泰姆	Ground Pin. Care must be taken in layout. This pin should be2CR嘉泰姆 placed outside of the Schottky Diode to output capacitor2CR嘉泰姆 ground path to prevent switching current spikes from inducing2CR嘉泰姆 voltage noise into CXSD6260.2CR嘉泰姆
22CR嘉泰姆	FB2CR嘉泰姆	Feedback Pin (FB). Through an external resistor divider2CR嘉泰姆 network, FB senses the output voltage and regulates it. The2CR嘉泰姆 feedback threshold voltage is 1.25V.2CR嘉泰姆
32CR嘉泰姆	SW2CR嘉泰姆	Power Switch Output Pin (SW). SW is the switch node that2CR嘉泰姆 supplies power to the output.2CR嘉泰姆
42CR嘉泰姆	VC2CR嘉泰姆	Internal Voltage Regulator Bypass Capacity. In typical system2CR嘉泰姆 application, The VC pin connect a 1uf capacity to VIN.2CR嘉泰姆
52CR嘉泰姆	VIN2CR嘉泰姆	Supply Voltage Input Pin. CXSD6260 operates from a 8V to 36V2CR嘉泰姆 DC voltage. Bypass Vin to GND with a suitably large2CR嘉泰姆 capacitor to eliminate noise on the input.2CR嘉泰姆
