一,产品概述(General Description) Ut1嘉泰姆
The CXSD61008 is a 380KHz fixed frequency PWM buck (step-down) DC/DC Ut1嘉泰姆
converter,capable of driving a 2A load with high efficiency, low ripple and Ut1嘉泰姆
excellent line and load regulation. Requiring a minimum number of external Ut1嘉泰姆
components, the regulator is simple to use and include internal frequency Ut1嘉泰姆
compensation and a fixed-frequency oscillator.The PWM control circuit is Ut1嘉泰姆
able to adjust the duty ratio linearly from 0 to 100%. An enablefunction, an Ut1嘉泰姆
over current protection function is built inside. When short protection function Ut1嘉泰姆
happens, the operation frequency will be reduced from 380KHz to 80KHz. AnUt1嘉泰姆
internal compensation block is built in to minimize external component count.Ut1嘉泰姆

VINUt1嘉泰姆 |
Supply Voltage Input Pin.CXSD61008 operates from a 3.6V to 18V DC voltage. Bypass Vin to GND with a suitably large capacitor to eliminate noise on the input.Ut1嘉泰姆 |

SWUt1嘉泰姆 |
Power Switch Output Pin (SW). Output is the switch node that supplies power to the output.Ut1嘉泰姆 |

GNDUt1嘉泰姆 |
Ground Pin. Care must be taken in layout. This pin should be placed outside of the Schottky Diode to output capacitor ground path to prevent switching current spikes from inducing voltage noise into CXSD61008.Ut1嘉泰姆 |

ENUt1嘉泰姆 |
Enable Pin. Drive EN pin low to turn off the device, drive it high to turn it on. Floating is default high.Ut1嘉泰姆 |
