一,产品概述(General Description) J4O嘉泰姆

The CXSD61066 is a 180 KHz fixed frequency PWM buck (step-down) DC/DCJ4O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.J4O嘉泰姆
The PWM control circuit is able to adjust the duty ratio linearly fromJ4O嘉泰姆

0 to 100%.An over current protection function is built inside.WhenJ4O嘉泰姆

short protection function happens, the operation frequency willJ4O嘉泰姆

be reduced from 180KHz to 48KHz. An internal compensation blockJ4O嘉泰姆

is built in to minimize external component count.J4O嘉泰姆
二.产品特点(Features)J4O嘉泰姆

1.)Wide 8V to 36V Input Voltage RangeJ4O嘉泰姆

Pin NumberJ4O嘉泰姆	Pin NameJ4O嘉泰姆	DescriptionJ4O嘉泰姆
1J4O嘉泰姆	GNDJ4O嘉泰姆	Ground Pin. Care must be taken in layout. This pin should beJ4O嘉泰姆 placed outside of the Schottky Diode to output capacitorJ4O嘉泰姆 ground path to prevent switching current spikes from inducingJ4O嘉泰姆 voltage noise into CXSD61057.J4O嘉泰姆
2J4O嘉泰姆	FBJ4O嘉泰姆	Feed CXSD61057 n (FB). Through an external resistor dividerJ4O嘉泰姆 network, FB senses the output voltage and regulates it. TheJ4O嘉泰姆 feedback threshold voltage is 1.25V.J4O嘉泰姆
3J4O嘉泰姆	SWJ4O嘉泰姆	Power Switch Output Pin (SW). SW is the switch node thatJ4O嘉泰姆 supplies power to the output.J4O嘉泰姆
4J4O嘉泰姆	VCJ4O嘉泰姆	Internal Voltage Regulator Bypass Capacity. In typical systemJ4O嘉泰姆 application, The VC pin connect a 1uf capacity to VIN.J4O嘉泰姆
5J4O嘉泰姆	VINJ4O嘉泰姆	Supply Voltage Input Pin. CXSD61057 operates from a 8V to 36VJ4O嘉泰姆 DC voltage. Bypass Vin to GND with a suitably largeJ4O嘉泰姆 capacitor to eliminate noise on the input.J4O嘉泰姆
