一,产品概述(General Description)         Fn6嘉泰姆


     The CXSD61066 is a 180 KHz fixed frequency PWM buck (step-down) DC/DCFn6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.Fn6嘉泰姆
    The PWM control circuit is able to adjust the duty ratio linearly fromFn6嘉泰姆

0 to 100%.An over current protection function is built inside.WhenFn6嘉泰姆

short protection function happens, the operation frequency willFn6嘉泰姆

be reduced from 180KHz to 48KHz. An internal compensation blockFn6嘉泰姆

is built in to minimize external component count.Fn6嘉泰姆

DescriptionFn6嘉泰姆

                1Fn6嘉泰姆

             GNDFn6嘉泰姆

 Ground Pin. Care must be taken in layout. This pin should beFn6嘉泰姆
placed outside of the Schottky Diode to output capacitorFn6嘉泰姆
ground path to prevent switching current spikes from inducingFn6嘉泰姆
voltage noise into CXSD61057.Fn6嘉泰姆

2Fn6嘉泰姆

 FBFn6嘉泰姆

 Feed CXSD61057 n (FB). Through an external resistor dividerFn6嘉泰姆
network, FB senses the output voltage and regulates it. TheFn6嘉泰姆
feedback threshold voltage is 1.25V.Fn6嘉泰姆

3Fn6嘉泰姆

        SWFn6嘉泰姆

Power Switch Output Pin (SW). SW is the switch node thatFn6嘉泰姆
supplies power to the output.Fn6嘉泰姆

 VCFn6嘉泰姆

  Internal Voltage Regulator Bypass Capacity. In typical systemFn6嘉泰姆
application, The VC pin connect a 1uf capacity to VIN.Fn6嘉泰姆

5Fn6嘉泰姆

VINFn6嘉泰姆

 Supply Voltage Input Pin. CXSD61057 operates from a 8V to 36VFn6嘉泰姆
DC voltage. Bypass Vin to GND with a suitably largeFn6嘉泰姆
capacitor to eliminate noise on the input.Fn6嘉泰姆
