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

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

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

short protection function happens, the operation frequency willgWt嘉泰姆

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

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

1.)Wide 8V to 36V Input Voltage RangegWt嘉泰姆
2.)Output Adjustable from 1.25V to 32VgWt嘉泰姆
3.)Maximum Duty Cycle 100%gWt嘉泰姆
4.)Minimum Drop Out 0.3VgWt嘉泰姆
5.)Fixed 180KHz Switching FrequencygWt嘉泰姆
6.)4A Constant Output Current CapabilitygWt嘉泰姆
7.)Internal Optimize Power MOSFETgWt嘉泰姆
8.)High efficiencygWt嘉泰姆
9.)Excellent line and load regulationgWt嘉泰姆
10.)Built in thermal shutdown functiongWt嘉泰姆
11.)Built in current limit functiongWt嘉泰姆
12.)Built in output short protection functiongWt嘉泰姆
13.)Available in TO-252 packagegWt嘉泰姆

DescriptiongWt嘉泰姆

                1gWt嘉泰姆

             GNDgWt嘉泰姆

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

2gWt嘉泰姆

 FBgWt嘉泰姆

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

3gWt嘉泰姆

        SWgWt嘉泰姆

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

 VCgWt嘉泰姆

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

5gWt嘉泰姆

VINgWt嘉泰姆

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