目录7.相关产品 产品概述 返回TOP The CXSD62124 is a 4A, asynchronous, step-down converter with integrated 80mW P-channel MOSFET. The device, with current-mode control scheme, can convert 4.5~26V input voltage to the output voltage adjustable from 0.8 to 90% VIN to provide excellent output voltage regulation. The CXSD62124 regulates the output voltage in automatic PSM/PWM mode operation, depending on the output current, for high efficiency operation over light to full load current. The CXSD62124 is also equipped with power-onreset, soft-start, and whole protections (under-voltage, over-temperature, and current-limit) into a single package. In shutdown mode, the supply current drops below 5mA. This device, available in a 8-pin SOP-8P package, provides a very compact system solution with minimal external components and good thermal conductance.产品特点 返回TOP · Wide Input Voltage from 4.5V to 26V · Output Current up to 4A · Adjustable Output Voltage from 0.8V to 90% VIN - 0.8V Reference Voltage - ±2.5% System Accuracy · 80mW Integrated P -Channel Power MOSFET · High Efficiency up to 91% - Pulse-Skipping Mode (PSM) / PWM Mode Operation · Current -Mode Operation - Stable with Ceramic Output Capacitors - Fast Transient Response · Power-On-Reset Monitoring · Fixed 380kHz Switching Frequency in PWM Mode · Built-in Digital Soft-Start · Output Current-Limit Protection with Frequency Foldback · 70% Under-Voltage Protection · Over-Temperature Protection ·<5mA Quiescent Current During Shutdown · Thermal-Enhanced SOP-8P Package · Lead Free and Green Devices Available (RoHS Compliant) 应用范围 返回TOP · LCD Monitor / TV · Set-Top Box · Portable DVD · Wireless LAN · ADSL, Switch HUB · Notebook Computer · Step-Down Converters Requiring High Efficiency and 4A Output Current 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
