一,产品概述(General Description) 3dA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 regulator3dA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.minimum3dA嘉泰姆

43dA嘉泰姆	VIN3dA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 3dA嘉泰姆 input.3dA嘉泰姆
5,63dA嘉泰姆	SW3dA嘉泰姆	Power Switch Output Pin (SW). Output is the switch node that supplies power to the output.3dA嘉泰姆
7,83dA嘉泰姆	GND3dA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 CXSD61009.3dA嘉泰姆
13dA嘉泰姆	FB3dA嘉泰姆	Feedback Pin (FB). Through an external resistor divider network, Feedback senses the output voltage and regulates it.The feedback threshold voltage is 0.8V.3dA嘉泰姆
23dA嘉泰姆	EN3dA嘉泰姆	Enable Pin. Drive EN pin low to turn off the device, drive it high to turn it on. Floating is default 3dA嘉泰姆 high.3dA嘉泰姆
