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

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

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

short protection function happens, the operation frequency willLKJ嘉泰姆

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

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

Pin NameLKJ嘉泰姆

DescriptionLKJ嘉泰姆

                1LKJ嘉泰姆

             GNDLKJ嘉泰姆

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

2LKJ嘉泰姆

 FBLKJ嘉泰姆

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

3LKJ嘉泰姆

        SWLKJ嘉泰姆

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

4LKJ嘉泰姆

 VCLKJ嘉泰姆

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

5LKJ嘉泰姆

VINLKJ嘉泰姆

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