CXSD61066

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)         PZy嘉泰姆


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

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

short protection function happens, the operation frequency willPZy嘉泰姆

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

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

Pin NumberPZy嘉泰姆

Pin NamePZy嘉泰姆

DescriptionPZy嘉泰姆

                1PZy嘉泰姆

             GNDPZy嘉泰姆

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

2PZy嘉泰姆

 FBPZy嘉泰姆

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

3PZy嘉泰姆

        SWPZy嘉泰姆

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

4PZy嘉泰姆

 VCPZy嘉泰姆

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

5PZy嘉泰姆

VINPZy嘉泰姆

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