一,产品概述(General Description) M5f嘉泰姆

The CXSD61066 is a 180 KHz fixed frequency PWM buck (step-down) DC/DCM5f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.M5f嘉泰姆
The PWM control circuit is able to adjust the duty ratio linearly fromM5f嘉泰姆

0 to 100%.An over current protection function is built inside.WhenM5f嘉泰姆

short protection function happens, the operation frequency willM5f嘉泰姆

be reduced from 180KHz to 48KHz. An internal compensation blockM5f嘉泰姆

is built in to minimize external component count.M5f嘉泰姆

Pin NumberM5f嘉泰姆	Pin NameM5f嘉泰姆	DescriptionM5f嘉泰姆
1M5f嘉泰姆	GNDM5f嘉泰姆	Ground Pin. Care must be taken in layout. This pin should beM5f嘉泰姆 placed outside of the Schottky Diode to output capacitorM5f嘉泰姆 ground path to prevent switching current spikes from inducingM5f嘉泰姆 voltage noise into CXSD61057.M5f嘉泰姆
2M5f嘉泰姆	FBM5f嘉泰姆	Feed CXSD61057 n (FB). Through an external resistor dividerM5f嘉泰姆 network, FB senses the output voltage and regulates it. TheM5f嘉泰姆 feedback threshold voltage is 1.25V.M5f嘉泰姆
3M5f嘉泰姆	SWM5f嘉泰姆	Power Switch Output Pin (SW). SW is the switch node thatM5f嘉泰姆 supplies power to the output.M5f嘉泰姆
4M5f嘉泰姆	VCM5f嘉泰姆	Internal Voltage Regulator Bypass Capacity. In typical systemM5f嘉泰姆 application, The VC pin connect a 1uf capacity to VIN.M5f嘉泰姆
5M5f嘉泰姆	VINM5f嘉泰姆	Supply Voltage Input Pin. CXSD61057 operates from a 8V to 36VM5f嘉泰姆 DC voltage. Bypass Vin to GND with a suitably largeM5f嘉泰姆 capacitor to eliminate noise on the input.M5f嘉泰姆
