一,产品概述(General Description) H4X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.H4X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.H4X嘉泰姆

PinH4X嘉泰姆 No.H4X嘉泰姆	NAMEH4X嘉泰姆	DescriptionH4X嘉泰姆
1H4X嘉泰姆	HSBH4X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.H4X嘉泰姆
2H4X嘉泰姆	INH4X嘉泰姆	Power Supply Input. Bypass this pin with a 10μF ceramic capacitor to GND, placed as close to the IC as possible.H4X嘉泰姆
3H4X嘉泰姆	SWH4X嘉泰姆	Power Switching Output to External Inductor.H4X嘉泰姆
4H4X嘉泰姆	GNDH4X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.H4X嘉泰姆
5H4X嘉泰姆	FBH4X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.H4X嘉泰姆

九,功能概述H4X嘉泰姆

CV/CC Loop RegulationH4X嘉泰姆
As seen in Functional Block Diagram, the CXSD61022A isH4X嘉泰姆
a Constant On Time (COT) mode pulse widthH4X嘉泰姆
modulation (PWM) converter with CC and CV control.H4X嘉泰姆
The converter operates as follows:H4X嘉泰姆
The main loop of CXSD61022A uses a COT mode controlH4X嘉泰姆
which provides a very fast transient response with noH4X嘉泰姆
external component and no need loop compensation.H4X嘉泰姆
The CXSD61022A also adopt a proprietary circuit thatH4X嘉泰姆
ensures enable use very low ESR capacitor to maintainH4X嘉泰姆
loop stability.H4X嘉泰姆
turns on. The high side MOSFET is turn off afterH4X嘉泰姆
internal one shot timer expires. This one shot time isH4X嘉泰姆
set by VIN and VOUT to maintain a constant frequency.H4X嘉泰姆
The one shot timer is reset and high side MOSFETH4X嘉泰姆
turns on again when feedback voltage falls below theH4X嘉泰姆
reference voltage. An internal ramp is generating toH4X嘉泰姆
simulate output ripple, eliminating the need for ESRH4X嘉泰姆
induced output ripple from COT control mode. WhenH4X嘉泰姆
high side MOSFET turns off, the SW node of theH4X嘉泰姆
inductor swings to a diode voltage below ground,H4X嘉泰姆
causing the inductor current to decrease and magneticH4X嘉泰姆
energy to be transferred to output. This state continuesH4X嘉泰姆
until the next cycle start againH4X嘉泰姆
