一,产品概述(General Description) sVu嘉泰姆

The CXSD61066 is a 180 KHz fixed frequency PWM buck (step-down) DC/DCsVu嘉泰姆
converter,capable of driving a 4A load with high efficiency, low ripple and excellent line and load regulation.Requiring a minimumnumber of external components, the regulator is simple to use and include internal frequency compensation and a fixed-frequency oscillator.sVu嘉泰姆
The PWM control circuit is able to adjust the duty ratio linearly fromsVu嘉泰姆

0 to 100%.An over current protection function is built inside.WhensVu嘉泰姆

short protection function happens, the operation frequency willsVu嘉泰姆

be reduced from 180KHz to 48KHz. An internal compensation blocksVu嘉泰姆

is built in to minimize external component count.sVu嘉泰姆

Pin NumbersVu嘉泰姆	Pin NamesVu嘉泰姆	DescriptionsVu嘉泰姆
1sVu嘉泰姆	GNDsVu嘉泰姆	Ground Pin. Care must be taken in layout. This pin should besVu嘉泰姆 placed outside of the Schottky Diode to output capacitorsVu嘉泰姆 ground path to prevent switching current spikes from inducingsVu嘉泰姆 voltage noise into CXSD61057.sVu嘉泰姆
2sVu嘉泰姆	FBsVu嘉泰姆	Feed CXSD61057 n (FB). Through an external resistor dividersVu嘉泰姆 network, FB senses the output voltage and regulates it. ThesVu嘉泰姆 feedback threshold voltage is 1.25V.sVu嘉泰姆
3sVu嘉泰姆	SWsVu嘉泰姆	Power Switch Output Pin (SW). SW is the switch node thatsVu嘉泰姆 supplies power to the output.sVu嘉泰姆
4sVu嘉泰姆	VCsVu嘉泰姆	Internal Voltage Regulator Bypass Capacity. In typical systemsVu嘉泰姆 application, The VC pin connect a 1uf capacity to VIN.sVu嘉泰姆
5sVu嘉泰姆	VINsVu嘉泰姆	Supply Voltage Input Pin. CXSD61057 operates from a 8V to 36VsVu嘉泰姆 DC voltage. Bypass Vin to GND with a suitably largesVu嘉泰姆 capacitor to eliminate noise on the input.sVu嘉泰姆
