一,产品概述(General Description) 1Na嘉泰姆

The CXSD61007 is a 150 KHz fixed frequency PWM buck (step-down)1Na嘉泰姆
DC/DC converter,capable of driving a 2A load with highefficiency, low1Na嘉泰姆
ripple and excellent line and load regulation. Requiring a minimum1Na嘉泰姆
number of external components, the regulator is simple to use and1Na嘉泰姆
include internal frequency compensation and a fixed-frequency1Na嘉泰姆
oscillator.1Na嘉泰姆
The PWM control circuit is able to adjust the duty ratio linearly1Na嘉泰姆
from 0 to 100%. An enable function, an over current protection function1Na嘉泰姆

is built inside. When second current limit function happens, the operation 1Na嘉泰姆

frequency will be reduced from 150KHz to 50KHz. An internal compensation1Na嘉泰姆

block is built in to minimize external component count.1Na嘉泰姆

Pin Number1Na嘉泰姆	Pin Name1Na嘉泰姆	Description1Na嘉泰姆
11Na嘉泰姆	VIN1Na嘉泰姆	Supply Voltage Input Pin. CXSD61007 operates from a 4.5V to1Na嘉泰姆 40V DC voltage. Bypass Vin to GND with a suitably large1Na嘉泰姆 capacitor to eliminate noise on the input.1Na嘉泰姆
21Na嘉泰姆	OUTPUT1Na嘉泰姆	Power Switch Output Pin (SW). Output is the switch node that1Na嘉泰姆 supplies power to the output.1Na嘉泰姆
5~81Na嘉泰姆	GND1Na嘉泰姆	Ground Pin. Care must be taken in layout. This pin should be1Na嘉泰姆 placed outside of the Schottky Diode to output capacitor1Na嘉泰姆 ground path to prevent switching current spikes from inducing1Na嘉泰姆 voltage noise into CXSD61007.1Na嘉泰姆
31Na嘉泰姆	FEEDBACK1Na嘉泰姆	Feedback Pin (FB). Through an external resistor divider1Na嘉泰姆 network, Feedback senses the output voltage and regulates it.1Na嘉泰姆 The feedback threshold voltage is 1.23V.1Na嘉泰姆
41Na嘉泰姆	ON/OFF1Na嘉泰姆	Enable Pin. Drive ON/OFF pin low to turn on the device, drive1Na嘉泰姆 it high to turn it off. Floating is default low.1Na嘉泰姆
