一,产品概述(General Description) weU嘉泰姆

CXSD61022A is a wide input voltage, high efficiency CC step-down DC/DC converter that operates in either CV (Constant Output Voltage) mode or CC (Constant Output Current) mode. CXSD61022A provides up to 2.5A output current at 125kHz switching frequency.weU嘉泰姆
CXSD61022A provides OVP pin for output over voltage protection.Protection features include cycle-by-cycle current limit,thermal shutdown, and frequency foldback at short circuit. The devices are available in a SOP-8EP package and require very few external devices for operation.weU嘉泰姆

PinweU嘉泰姆 No.weU嘉泰姆	NAMEweU嘉泰姆	DescriptionweU嘉泰姆
1weU嘉泰姆	HSBweU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.weU嘉泰姆
2weU嘉泰姆	INweU嘉泰姆	Power Supply Input. Bypass this pin with a 10μF ceramic capacitor to GND, placed as close to the IC as possible.weU嘉泰姆
3weU嘉泰姆	SWweU嘉泰姆	Power Switching Output to External Inductor.weU嘉泰姆
4weU嘉泰姆	GNDweU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.weU嘉泰姆
5weU嘉泰姆	FBweU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.weU嘉泰姆

九,功能概述weU嘉泰姆

CV/CC Loop RegulationweU嘉泰姆
As seen in Functional Block Diagram, the CXSD61022A isweU嘉泰姆
a Constant On Time (COT) mode pulse widthweU嘉泰姆
modulation (PWM) converter with CC and CV control.weU嘉泰姆
The converter operates as follows:weU嘉泰姆
The main loop of CXSD61022A uses a COT mode controlweU嘉泰姆
which provides a very fast transient response with noweU嘉泰姆
external component and no need loop compensation.weU嘉泰姆
The CXSD61022A also adopt a proprietary circuit thatweU嘉泰姆
ensures enable use very low ESR capacitor to maintainweU嘉泰姆
loop stability.weU嘉泰姆
turns on. The high side MOSFET is turn off afterweU嘉泰姆
internal one shot timer expires. This one shot time isweU嘉泰姆
set by VIN and VOUT to maintain a constant frequency.weU嘉泰姆
The one shot timer is reset and high side MOSFETweU嘉泰姆
turns on again when feedback voltage falls below theweU嘉泰姆
reference voltage. An internal ramp is generating toweU嘉泰姆
simulate output ripple, eliminating the need for ESRweU嘉泰姆
induced output ripple from COT control mode. WhenweU嘉泰姆
high side MOSFET turns off, the SW node of theweU嘉泰姆
inductor swings to a diode voltage below ground,weU嘉泰姆
causing the inductor current to decrease and magneticweU嘉泰姆
energy to be transferred to output. This state continuesweU嘉泰姆
until the next cycle start againweU嘉泰姆
