一,产品概述(General Description) Ykh嘉泰姆

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

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

short protection function happens, the operation frequency willYkh嘉泰姆

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

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

1.)Wide 8V to 36V Input Voltage RangeYkh嘉泰姆
2.)Output Adjustable from 1.25V to 32VYkh嘉泰姆
3.)Maximum Duty Cycle 100%Ykh嘉泰姆
4.)Minimum Drop Out 0.3VYkh嘉泰姆
5.)Fixed 180KHz Switching FrequencyYkh嘉泰姆

Ykh嘉泰姆

Pin NumberYkh嘉泰姆	Pin NameYkh嘉泰姆	DescriptionYkh嘉泰姆
1Ykh嘉泰姆	GNDYkh嘉泰姆	Ground Pin. Care must be taken in layout. This pin should beYkh嘉泰姆 placed outside of the Schottky Diode to output capacitorYkh嘉泰姆 ground path to prevent switching current spikes from inducingYkh嘉泰姆 voltage noise into CXSD61057.Ykh嘉泰姆
2Ykh嘉泰姆	FBYkh嘉泰姆	Feed CXSD61057 n (FB). Through an external resistor dividerYkh嘉泰姆 network, FB senses the output voltage and regulates it. TheYkh嘉泰姆 feedback threshold voltage is 1.25V.Ykh嘉泰姆
3Ykh嘉泰姆	SWYkh嘉泰姆	Power Switch Output Pin (SW). SW is the switch node thatYkh嘉泰姆 supplies power to the output.Ykh嘉泰姆
4Ykh嘉泰姆	VCYkh嘉泰姆	Internal Voltage Regulator Bypass Capacity. In typical systemYkh嘉泰姆 application, The VC pin connect a 1uf capacity to VIN.Ykh嘉泰姆
5Ykh嘉泰姆	VINYkh嘉泰姆	Supply Voltage Input Pin. CXSD61057 operates from a 8V to 36VYkh嘉泰姆 DC voltage. Bypass Vin to GND with a suitably largeYkh嘉泰姆 capacitor to eliminate noise on the input.Ykh嘉泰姆
