PinUfu嘉泰姆 No.Ufu嘉泰姆	NAMEUfu嘉泰姆	DescriptionUfu嘉泰姆
1Ufu嘉泰姆	HSBUfu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.Ufu嘉泰姆
2Ufu嘉泰姆	INUfu嘉泰姆	Power Supply Input. Bypass this pin with a 10μF ceramic capacitor to GND, placed as close to the IC as possible.Ufu嘉泰姆
3Ufu嘉泰姆	SWUfu嘉泰姆	Power Switching Output to External Inductor.Ufu嘉泰姆
4Ufu嘉泰姆	GNDUfu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.Ufu嘉泰姆
5Ufu嘉泰姆	FBUfu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.Ufu嘉泰姆

九,功能概述Ufu嘉泰姆

CV/CC Loop RegulationUfu嘉泰姆
As seen in Functional Block Diagram, the CXSD61022A isUfu嘉泰姆
a Constant On Time (COT) mode pulse widthUfu嘉泰姆
modulation (PWM) converter with CC and CV control.Ufu嘉泰姆
The converter operates as follows:Ufu嘉泰姆
The main loop of CXSD61022A uses a COT mode controlUfu嘉泰姆
which provides a very fast transient response with noUfu嘉泰姆
external component and no need loop compensation.Ufu嘉泰姆
The CXSD61022A also adopt a proprietary circuit thatUfu嘉泰姆
ensures enable use very low ESR capacitor to maintainUfu嘉泰姆
loop stability.Ufu嘉泰姆
turns on. The high side MOSFET is turn off afterUfu嘉泰姆
internal one shot timer expires. This one shot time isUfu嘉泰姆
set by VIN and VOUT to maintain a constant frequency.Ufu嘉泰姆
The one shot timer is reset and high side MOSFETUfu嘉泰姆
turns on again when feedback voltage falls below theUfu嘉泰姆
reference voltage. An internal ramp is generating toUfu嘉泰姆
simulate output ripple, eliminating the need for ESRUfu嘉泰姆
induced output ripple from COT control mode. WhenUfu嘉泰姆
high side MOSFET turns off, the SW node of theUfu嘉泰姆
inductor swings to a diode voltage below ground,Ufu嘉泰姆
causing the inductor current to decrease and magneticUfu嘉泰姆
energy to be transferred to output. This state continuesUfu嘉泰姆
until the next cycle start againUfu嘉泰姆
