一,产品概述(General Description) Km7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.Km7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.Km7嘉泰姆

PinKm7嘉泰姆 No.Km7嘉泰姆	NAMEKm7嘉泰姆	DescriptionKm7嘉泰姆
1Km7嘉泰姆	HSBKm7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.Km7嘉泰姆
2Km7嘉泰姆	INKm7嘉泰姆	Power Supply Input. Bypass this pin with a 10μF ceramic capacitor to GND, placed as close to the IC as possible.Km7嘉泰姆
3Km7嘉泰姆	SWKm7嘉泰姆	Power Switching Output to External Inductor.Km7嘉泰姆
4Km7嘉泰姆	GNDKm7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.Km7嘉泰姆
5Km7嘉泰姆	FBKm7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.Km7嘉泰姆
6Km7嘉泰姆	LCOMPKm7嘉泰姆	Output cable resistance compensation.Km7嘉泰姆
7Km7嘉泰姆	OVP/ENKm7嘉泰姆	CXSD61022A: OVP input. If the voltage at this pin exceeds 1.25V, the IC shuts down high-side switch.CXSD61022B: EN input. If the voltage at this pin is below 1.5V, the IC remains shut-off.Km7嘉泰姆
8Km7嘉泰姆	ISETKm7嘉泰姆	Output Current Setting Pin. Connect a resistor from ISET to GND to program the out putcurrent.Km7嘉泰姆

九,功能概述Km7嘉泰姆

CV/CC Loop RegulationKm7嘉泰姆
As seen in Functional Block Diagram, the CXSD61022A isKm7嘉泰姆
a Constant On Time (COT) mode pulse widthKm7嘉泰姆
modulation (PWM) converter with CC and CV control.Km7嘉泰姆
The converter operates as follows:Km7嘉泰姆
The main loop of CXSD61022A uses a COT mode controlKm7嘉泰姆
which provides a very fast transient response with noKm7嘉泰姆
external component and no need loop compensation.Km7嘉泰姆
The CXSD61022A also adopt a proprietary circuit thatKm7嘉泰姆
ensures enable use very low ESR capacitor to maintainKm7嘉泰姆
loop stability.Km7嘉泰姆
turns on. The high side MOSFET is turn off afterKm7嘉泰姆
internal one shot timer expires. This one shot time isKm7嘉泰姆
set by VIN and VOUT to maintain a constant frequency.Km7嘉泰姆
The one shot timer is reset and high side MOSFETKm7嘉泰姆
turns on again when feedback voltage falls below theKm7嘉泰姆
reference voltage. An internal ramp is generating toKm7嘉泰姆
simulate output ripple, eliminating the need for ESRKm7嘉泰姆
induced output ripple from COT control mode. WhenKm7嘉泰姆
high side MOSFET turns off, the SW node of theKm7嘉泰姆
inductor swings to a diode voltage below ground,Km7嘉泰姆
causing the inductor current to decrease and magneticKm7嘉泰姆
energy to be transferred to output. This state continuesKm7嘉泰姆
until the next cycle start againKm7嘉泰姆
