The CXCH7606 is a 180 KHz fixed frequency PWM buck (step-down)
DC/DC converter,capable of driving a 2.5A 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.
The PWM control circuit is able to adjust the duty ratio linearly from
0 to 100%. An over current protection function is built inside When
short protection function happens, the operation frequency will be reduced from 180KHz to 48KHz. An internal compensation block is built in to
minimize external component count.

Description7ug嘉泰姆

17ug嘉泰姆

FB7ug嘉泰姆

Feedback Pin (FB). Through an external resistor divider7ug嘉泰姆
network, FB senses the output voltage and regulates it. The7ug嘉泰姆
feedback threshold voltage is 1.25V.7ug嘉泰姆

VC7ug嘉泰姆

Internal Voltage Regulator Bypass Capacity. In typical system7ug嘉泰姆
application, The VC pin connect a 1uf capacity to VIN.7ug嘉泰姆

47ug嘉泰姆

VIN7ug嘉泰姆

Supply Voltage Input Pin. CXCH7606 operates from a 8V to 36V7ug嘉泰姆
DC voltage. Bypass Vin to GND with a suitably large7ug嘉泰姆
capacitor to eliminate noise on the input.7ug嘉泰姆

5,67ug嘉泰姆

SW7ug嘉泰姆

Power Switch Output Pin (SW). SW is the switch node that7ug嘉泰姆
supplies power to the output.7ug嘉泰姆

7,87ug嘉泰姆

GND7ug嘉泰姆

Ground Pin. Care must be taken in layout. This pin should be7ug嘉泰姆
placed outside of the Schottky Diode to output capacitor7ug嘉泰姆
ground path to prevent switching current spikes from inducing7ug嘉泰姆
voltage noise into CXCH7606.7ug嘉泰姆
