双相动态电压COT-Buck-PWM控制器CXSD62119双相PWM控制芯片为先进的图形卡和主板应用提供了一种精确的电压调节系统

The CXSD62119 is a dual-phase PWM control IC which provides a precision voltage regulation system for advanced graphic card and motherboard applications. The integration of dual-phase power MOSFET drivers into the controller IC and reduces the number of external parts for a cost and space saving power management solution. The CXSD62119 uses a constant on time architecture control, and results in excellent transient response and accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Mode (PFM), the CXSD62119 provides very high efficiency over light to heavy loads with loading modulated switching frequencies. In PWM Mode, the converter works nearly at constant frequency for low-noise requirements. The device uses the voltage across the low side RDS(ON) for current sensing achieves high efficiency. The device integrates adjustable load line voltage positioning (droop) and adopts low side RDS(ON) for channel-current balance. The CXSD62119 also implement a VID control operation in which the feedback voltage is regulated and tracks external input reference voltage. This controller protection features include over-temperature (OTP), over-voltage (OVP), under-voltage (UVP) and overcurrent protections (OCP). The device also provides a power-on-reset function and a external programmable soft-start to prevent wrong operation and limit the input surge current during power-on or start-up. The CXSD62119 is available in TQFN 3x3-20 packages.
