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

Pinpns嘉泰姆 No.pns嘉泰姆	NAMEpns嘉泰姆	Descriptionpns嘉泰姆
1pns嘉泰姆	HSBpns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.pns嘉泰姆
2pns嘉泰姆	INpns嘉泰姆	Power Supply Input. Bypass this pin with a 10μF ceramic capacitor to GND, placed as close to the IC as possible.pns嘉泰姆
3pns嘉泰姆	SWpns嘉泰姆	Power Switching Output to External Inductor.pns嘉泰姆
4pns嘉泰姆	GNDpns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.pns嘉泰姆
5pns嘉泰姆	FBpns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.pns嘉泰姆

九,功能概述pns嘉泰姆

CV/CC Loop Regulationpns嘉泰姆
As seen in Functional Block Diagram, the CXSD61022A ispns嘉泰姆
a Constant On Time (COT) mode pulse widthpns嘉泰姆
modulation (PWM) converter with CC and CV control.pns嘉泰姆
The converter operates as follows:pns嘉泰姆
The main loop of CXSD61022A uses a COT mode controlpns嘉泰姆
which provides a very fast transient response with nopns嘉泰姆
external component and no need loop compensation.pns嘉泰姆
The CXSD61022A also adopt a proprietary circuit thatpns嘉泰姆
ensures enable use very low ESR capacitor to maintainpns嘉泰姆
loop stability.pns嘉泰姆
turns on. The high side MOSFET is turn off afterpns嘉泰姆
internal one shot timer expires. This one shot time ispns嘉泰姆
set by VIN and VOUT to maintain a constant frequency.pns嘉泰姆
The one shot timer is reset and high side MOSFETpns嘉泰姆
turns on again when feedback voltage falls below thepns嘉泰姆
reference voltage. An internal ramp is generating topns嘉泰姆
simulate output ripple, eliminating the need for ESRpns嘉泰姆
induced output ripple from COT control mode. Whenpns嘉泰姆
high side MOSFET turns off, the SW node of thepns嘉泰姆
inductor swings to a diode voltage below ground,pns嘉泰姆
causing the inductor current to decrease and magneticpns嘉泰姆
energy to be transferred to output. This state continuespns嘉泰姆
until the next cycle start againpns嘉泰姆
