PinM7h嘉泰姆 No.M7h嘉泰姆	NAMEM7h嘉泰姆	DescriptionM7h嘉泰姆
1M7h嘉泰姆	HSBM7h嘉泰姆	High Side Bias Pin. This provides power to the internal high-side MOSFET gate driver.Connect a 100nF capacitor from HSB pin to SW pin.M7h嘉泰姆
2M7h嘉泰姆	INM7h嘉泰姆	Power Supply Input. Bypass this pin with a 10μF ceramic capacitor to GND, placed as close to the IC as possible.M7h嘉泰姆
3M7h嘉泰姆	SWM7h嘉泰姆	Power Switching Output to External Inductor.M7h嘉泰姆
4M7h嘉泰姆	GNDM7h嘉泰姆	Ground. Connect this pin to a large PCB copper area for best heat dissipation. Return FB,COMP, and ISET to this GND, and connect this GND to power GND at a single point for best noise immunity.M7h嘉泰姆
5M7h嘉泰姆	FBM7h嘉泰姆	Feedback Input. The voltage at this pin is regulated to 0.800V. Connect to the resistor divider between output and GND to set the output voltage.M7h嘉泰姆

九,功能概述M7h嘉泰姆

CV/CC Loop RegulationM7h嘉泰姆
As seen in Functional Block Diagram, the CXSD61022A isM7h嘉泰姆
a Constant On Time (COT) mode pulse widthM7h嘉泰姆
modulation (PWM) converter with CC and CV control.M7h嘉泰姆
The converter operates as follows:M7h嘉泰姆
The main loop of CXSD61022A uses a COT mode controlM7h嘉泰姆
which provides a very fast transient response with noM7h嘉泰姆
external component and no need loop compensation.M7h嘉泰姆
The CXSD61022A also adopt a proprietary circuit thatM7h嘉泰姆
ensures enable use very low ESR capacitor to maintainM7h嘉泰姆
loop stability.M7h嘉泰姆
turns on. The high side MOSFET is turn off afterM7h嘉泰姆
internal one shot timer expires. This one shot time isM7h嘉泰姆
set by VIN and VOUT to maintain a constant frequency.M7h嘉泰姆
The one shot timer is reset and high side MOSFETM7h嘉泰姆
turns on again when feedback voltage falls below theM7h嘉泰姆
reference voltage. An internal ramp is generating toM7h嘉泰姆
simulate output ripple, eliminating the need for ESRM7h嘉泰姆
induced output ripple from COT control mode. WhenM7h嘉泰姆
high side MOSFET turns off, the SW node of theM7h嘉泰姆
inductor swings to a diode voltage below ground,M7h嘉泰姆
causing the inductor current to decrease and magneticM7h嘉泰姆
energy to be transferred to output. This state continuesM7h嘉泰姆
until the next cycle start againM7h嘉泰姆
