The CXCH7610 is a 150 KHz fixed frequency PWM buck (step-down)
DC/DC converter,capable of driving a 3.2A 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.
The CXCH7610 built in output short protection function. When short
protection function happens, the chip will be shutdown. An internal
compensation block is built in to minimize external component count.

VCiS7嘉泰姆

Internal Voltage Regulator Bypass Capacity. In typical systemiS7嘉泰姆
application, The VC pin connect a 1uf capacity to VIN.iS7嘉泰姆

5iS7嘉泰姆

VINiS7嘉泰姆

Supply Voltage Input Pin. CXCH7610 operates from 8V to 40ViS7嘉泰姆
DC voltage. Bypass Vin to GND with a suitably largeiS7嘉泰姆
capacitor to eliminate noise on the input.iS7嘉泰姆
