          The CXSD61016 is a 150KHz fixed frequency PWM buck

 (step-down) DC/DC converter,capable of driving a 2A load with

 high efficiency, 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.72C嘉泰姆
         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. An internal compensation block is built in to minimize external component count.

Pin Number Pin Name Description
1,2 SW Power Switch Output Pin (SW). Output is the switch node that72C嘉泰姆
supplies power to the output.
3 GND Ground Pin.(Note: Connected the back exposed PAD to Pin3.)
4 FB Feedback Pin (FB). Through an external resistor divider72C嘉泰姆
network, Feedback senses the output voltage and regulates it.72C嘉泰姆
The feedback threshold voltage is 1.235V.
5 CS Output Current Sense Pin; (Iload=0.155V/Rcs)
6 EN Enable Pin. Drive EN pin low to turn on the device, drive it high72C嘉泰姆
to turn it off. Floating is default low.
7,8 VIN Supply Voltage Input Pin. CXSD61016 operates from a 4.5V to 40V DC voltage. Bypass Vin to GND with a suitably large capacitor72C嘉泰姆
to eliminate noise on the input.
