一,产品概述(General Description) 6rn嘉泰姆

The CXSD61007 is a 150 KHz fixed frequency PWM buck (step-down)6rn嘉泰姆
DC/DC converter,capable of driving a 2A load with highefficiency, low6rn嘉泰姆
ripple and excellent line and load regulation. Requiring a minimum6rn嘉泰姆
number of external components, the regulator is simple to use and6rn嘉泰姆
include internal frequency compensation and a fixed-frequency6rn嘉泰姆
oscillator.6rn嘉泰姆
The PWM control circuit is able to adjust the duty ratio linearly6rn嘉泰姆
from 0 to 100%. An enable function, an over current protection function6rn嘉泰姆

is built inside. When second current limit function happens, the operation 6rn嘉泰姆

frequency will be reduced from 150KHz to 50KHz. An internal compensation6rn嘉泰姆

block is built in to minimize external component count.6rn嘉泰姆

Pin Number6rn嘉泰姆	Pin Name6rn嘉泰姆	Description6rn嘉泰姆
16rn嘉泰姆	VIN6rn嘉泰姆	Supply Voltage Input Pin. CXSD61007 operates from a 4.5V to6rn嘉泰姆 40V DC voltage. Bypass Vin to GND with a suitably large6rn嘉泰姆 capacitor to eliminate noise on the input.6rn嘉泰姆
26rn嘉泰姆	OUTPUT6rn嘉泰姆	Power Switch Output Pin (SW). Output is the switch node that6rn嘉泰姆 supplies power to the output.6rn嘉泰姆
5~86rn嘉泰姆	GND6rn嘉泰姆	Ground Pin. Care must be taken in layout. This pin should be6rn嘉泰姆 placed outside of the Schottky Diode to output capacitor6rn嘉泰姆 ground path to prevent switching current spikes from inducing6rn嘉泰姆 voltage noise into CXSD61007.6rn嘉泰姆
36rn嘉泰姆	FEEDBACK6rn嘉泰姆	Feedback Pin (FB). Through an external resistor divider6rn嘉泰姆 network, Feedback senses the output voltage and regulates it.6rn嘉泰姆 The feedback threshold voltage is 1.23V.6rn嘉泰姆
46rn嘉泰姆	ON/OFF6rn嘉泰姆	Enable Pin. Drive ON/OFF pin low to turn on the device, drive6rn嘉泰姆 it high to turn it off. Floating is default low.6rn嘉泰姆
