一,产品概述(General Description) 266嘉泰姆
266嘉泰姆
The CXSD6260 is a 180 KHz fixed frequency PWM buck (step-down)266嘉泰姆
DC/DC converter,capable of driving a 5A load with high efficiency, low ripple266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 266嘉泰姆
compensation and a fixed-frequency oscillator.266嘉泰姆
The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%.266嘉泰姆
An over current protection function is built inside.When short protection function266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 count266嘉泰姆

Pin Number266嘉泰姆	Pin Name266嘉泰姆	Description266嘉泰姆
1266嘉泰姆	GND266嘉泰姆	Ground Pin. Care must be taken in layout. This pin should be266嘉泰姆 placed outside of the Schottky Diode to output capacitor266嘉泰姆 ground path to prevent switching current spikes from inducing266嘉泰姆 voltage noise into CXSD6260.266嘉泰姆
2266嘉泰姆	FB266嘉泰姆	Feedback Pin (FB). Through an external resistor divider266嘉泰姆 network, FB senses the output voltage and regulates it. The266嘉泰姆 feedback threshold voltage is 1.25V.266嘉泰姆
3266嘉泰姆	SW266嘉泰姆	Power Switch Output Pin (SW). SW is the switch node that266嘉泰姆 supplies power to the output.266嘉泰姆
4266嘉泰姆	VC266嘉泰姆	Internal Voltage Regulator Bypass Capacity. In typical system266嘉泰姆 application, The VC pin connect a 1uf capacity to VIN.266嘉泰姆
5266嘉泰姆	VIN266嘉泰姆	Supply Voltage Input Pin. CXSD6260 operates from a 8V to 36V266嘉泰姆 DC voltage. Bypass Vin to GND with a suitably large266嘉泰姆 capacitor to eliminate noise on the input.266嘉泰姆
