一,产品概述(General Description)         ki2嘉泰姆

        The CXSD61009 is a 380KHz fixed frequency PWM buck (step-down) DC/DC converter,capable of driving a 3A load with high efficiency, low ripple and excellent line and load regulation. Requiring a number of external components, the regulatorki2嘉泰姆
is simple to use and include internal frequency    compensation and a fixed-frequency oscillator. The PWM control circuit is able to adjust the duty ratio linearly from 0 to 100%. An enable function, an over current protection function is built inside. When short protection function happens, the operation frequency will be reduced from 380KHz to 80KHz. An internal compensation block is built in to minimize external component count.minimumki2嘉泰姆

VINki2嘉泰姆

Supply Voltage Input Pin. CXSD61009 operates from a 3.6V to 18V DC voltage. Bypass Vin to GND with a suitably large capacitor to eliminate noise on the ki2嘉泰姆

GNDki2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 CXSD61009.ki2嘉泰姆
