20

The CXSD61066 is a 180 KHz fixed frequency PWM buck (step-down) DC/DC
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.

一,产品概述(General Description)         K7i嘉泰姆


     The CXSD61066 is a 180 KHz fixed frequency PWM buck (step-down) DC/DCK7i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.K7i嘉泰姆
    The PWM control circuit is able to adjust the duty ratio linearly fromK7i嘉泰姆

0 to 100%.An over current protection function is built inside.WhenK7i嘉泰姆

short protection function happens, the operation frequency willK7i嘉泰姆

be reduced from 180KHz to 48KHz. An internal compensation blockK7i嘉泰姆

is built in to minimize external component count.K7i嘉泰姆

Pin NameK7i嘉泰姆

DescriptionK7i嘉泰姆

                1K7i嘉泰姆

             GNDK7i嘉泰姆

 Ground Pin. Care must be taken in layout. This pin should beK7i嘉泰姆
placed outside of the Schottky Diode to output capacitorK7i嘉泰姆
ground path to prevent switching current spikes from inducingK7i嘉泰姆
voltage noise into CXSD61057.K7i嘉泰姆

2K7i嘉泰姆

 FBK7i嘉泰姆

 Feed CXSD61057 n (FB). Through an external resistor dividerK7i嘉泰姆
network, FB senses the output voltage and regulates it. TheK7i嘉泰姆
feedback threshold voltage is 1.25V.K7i嘉泰姆

3K7i嘉泰姆

        SWK7i嘉泰姆

Power Switch Output Pin (SW). SW is the switch node thatK7i嘉泰姆
supplies power to the output.K7i嘉泰姆

4K7i嘉泰姆

 VCK7i嘉泰姆

  Internal Voltage Regulator Bypass Capacity. In typical systemK7i嘉泰姆
application, The VC pin connect a 1uf capacity to VIN.K7i嘉泰姆

5K7i嘉泰姆

VINK7i嘉泰姆

 Supply Voltage Input Pin. CXSD61057 operates from a 8V to 36VK7i嘉泰姆
DC voltage. Bypass Vin to GND with a suitably largeK7i嘉泰姆
capacitor to eliminate noise on the input.K7i嘉泰姆
