目录7.相关产品 产品概述 返回TOP The CXSD62107 is a single-phase, constant-on-time, synchronous PWM controller, which drives N-channel MOSFETs. The CXSD62107 steps down high voltage to generate low-voltage chipset or RAM supplies in notebook computers. The CXSD62107 provides excellent transient response and accurate DC voltage output in either PFM or PWM Mode. In Pulse Frequency Mode (PFM), the CXSD62107 provides very high efficiency over light to heavy loads with loadingmodulated switching frequencies. In PWM Mode, the converter works nearly at constant frequency for low-noise requirements. The CXSD62107 is equipped with accurate positive currentlimit, output under-voltage, and output over-voltage protections, perfect for NB applications. The Power-OnReset function monitors the voltage on VCC and PVCC to prevent wrong operation during power-on. The CXSD62107 has a 1.2ms digital soft-start and built-in an integrated output discharge device for soft-stop. An internal integrated soft-start ramps up the output voltage with programmable slew rate to reduce the start-up current. A soft-stop function actively discharges the output capacitors. The CXSD62107 is available in 16pin TQFN package respectively.产品特点 返回TOP · Adjustable Output Voltage from +0.75V to +5.5V - 0.75V Reference Voltage - ±1% Accuracy Over-Temperature · Operates from An Input Battery Voltage Range of +1.8V to +28V · Power-On-Reset Monitoring on VCC Pin and PVCC Pin · Excellent Line and Load Transient Responses · PFM Mode for Increased Light Load Efficiency · Programmable PWM Frequency from 100kHz to 500kHz · Integrated MOSFET Drivers · Integrated Bootstrap Forward P-CH MOSFET · Adjustable Integrated Soft-Start and Soft-Stop · Selectable Forced PWM or Automatic PFM/PWM Mode · Power Good Monitoring · 70% Under-Voltage Protection · 125% Over-Voltage Protection · Adjustable Current-Limit Protection - Using Sense Low-Side MOSFET’s RDS(ON) · Over-Temperature Protection · TQFN3x3-16 Package · Lead Free and Green Devices Available (RoHS Compliant) 应用范围 返回TOP · Notebook · Table PC · Hand-Held Portable · AIO PC 技术规格书（产品PDF) 返回TOP 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持！ 产品封装图 返回TOP
