一,产品概述(General Description) 2jl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.2jl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.2jl嘉泰姆

九,功能概述2jl嘉泰姆

CV/CC Loop Regulation2jl嘉泰姆
As seen in Functional Block Diagram, the CXSD61022A is2jl嘉泰姆
a Constant On Time (COT) mode pulse width2jl嘉泰姆
modulation (PWM) converter with CC and CV control.2jl嘉泰姆
The converter operates as follows:2jl嘉泰姆
The main loop of CXSD61022A uses a COT mode control2jl嘉泰姆
which provides a very fast transient response with no2jl嘉泰姆
external component and no need loop compensation.2jl嘉泰姆
The CXSD61022A also adopt a proprietary circuit that2jl嘉泰姆
ensures enable use very low ESR capacitor to maintain2jl嘉泰姆
loop stability.2jl嘉泰姆
turns on. The high side MOSFET is turn off after2jl嘉泰姆
internal one shot timer expires. This one shot time is2jl嘉泰姆
set by VIN and VOUT to maintain a constant frequency.2jl嘉泰姆
The one shot timer is reset and high side MOSFET2jl嘉泰姆
turns on again when feedback voltage falls below the2jl嘉泰姆
reference voltage. An internal ramp is generating to2jl嘉泰姆
simulate output ripple, eliminating the need for ESR2jl嘉泰姆
induced output ripple from COT control mode. When2jl嘉泰姆
high side MOSFET turns off, the SW node of the2jl嘉泰姆
inductor swings to a diode voltage below ground,2jl嘉泰姆
causing the inductor current to decrease and magnetic2jl嘉泰姆
energy to be transferred to output. This state continues2jl嘉泰姆
until the next cycle start again2jl嘉泰姆
