一,产品概述(General Description) xMP嘉泰姆

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

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

short protection function happens, the operation frequency willxMP嘉泰姆

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

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

Pin NumberxMP嘉泰姆	Pin NamexMP嘉泰姆	DescriptionxMP嘉泰姆
1xMP嘉泰姆	GNDxMP嘉泰姆	Ground Pin. Care must be taken in layout. This pin should bexMP嘉泰姆 placed outside of the Schottky Diode to output capacitorxMP嘉泰姆 ground path to prevent switching current spikes from inducingxMP嘉泰姆 voltage noise into CXSD61057.xMP嘉泰姆
2xMP嘉泰姆	FBxMP嘉泰姆	Feed CXSD61057 n (FB). Through an external resistor dividerxMP嘉泰姆 network, FB senses the output voltage and regulates it. ThexMP嘉泰姆 feedback threshold voltage is 1.25V.xMP嘉泰姆
3xMP嘉泰姆	SWxMP嘉泰姆	Power Switch Output Pin (SW). SW is the switch node thatxMP嘉泰姆 supplies power to the output.xMP嘉泰姆
4xMP嘉泰姆	VCxMP嘉泰姆	Internal Voltage Regulator Bypass Capacity. In typical systemxMP嘉泰姆 application, The VC pin connect a 1uf capacity to VIN.xMP嘉泰姆
5xMP嘉泰姆	VINxMP嘉泰姆	Supply Voltage Input Pin. CXSD61057 operates from a 8V to 36VxMP嘉泰姆 DC voltage. Bypass Vin to GND with a suitably largexMP嘉泰姆 capacitor to eliminate noise on the input.xMP嘉泰姆
