目录7.相关产品 产品概述 返回TOP The CXSD62179 is a high efficiency monolithic synchronous buck regulator. CXSD62179 operates with a constant 1.5MHz switching frequency and using the inductor current as a controlled quantity in the current mode architecture. The 2.7V to 5.5V input voltage range makes the CXSD62179 ideally suited for single Li-Ion battery powered applications. 100% duty cycle provides low dropout operation, extending battery life in portable electrical devices. The internally fixed 1.5MHz operating frequency allows the use of small surface mount inductors and capacitors. The synchronous switches included inside increase the efficiency and eliminate the need for an external Schottky diode. The CXSD62179 is available in TSOT-23-6A package产品特点 返回TOP · 1A Output Current · Wide 2.7V~5.5V Input Voltage · Fixed 1.5MHz Switching Frequency · Low Dropout Operating at 100% duty cycle · Low 25mA Quiescent Current · Integrate Synchronous Rectifier · 0.6V Low Reference Voltage ·<0.5mA Input Current during Shutdown · Current-Mode Operation with Internal Compensation - Stable with Ceramic Output Capacitors - Fast Line Transient Response · Over-Voltage Protection · Under Voltage Protection · Over-Temperature Protection with Hysteresis · Available in a TSOT-23-6A Package · Halogen and Lead Free Available (RoHS Compliant) 应用范围 返回TOP · HD STB · BT Mouse · PND Instrument · Portable Instrument 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
