一,产品概述(General Description)
The CXSD61007 is a 150 KHz fixed frequency PWM buck (step-down)
DC/DC converter,capable of driving a 2A load with highefficiency, low
ripple and excellent line and load regulation. Requiring a minimum
number of external components, the regulator 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 second current limit function happens, the operation
frequency will be reduced from 150KHz to 50KHz. An internal compensation
block is built in to minimize external component count.
二.产品特点(Features)
1.)Wide 4.5V to 40V Input Voltage Range
2.)3.3V,5V,12V, and adjustable versions
3.)Output Adjustable from 1.23V to 37V
4.)Maximum Duty Cycle 100%
5.)Minimum Drop Out 1.5V
6.)Fixed 150KHz Switching Frequency
7.)2A Constant Output Current Capability
8.)Internal Optimize Power Transistor
9.)High efficiency
10.)Excellent line and load regulation
11.)TTL shutdown capability
12.)ON/OFF pin with hysteresis function
13.)Built in thermal shutdown function
14.)Built in current limit function
15.)Built in second current limit function
16.)Available in SOIC8 package
