目录产品概述 返回TOP The CXSU63033A is a synchronous, fixed frequency, step-up DC/DC converters delivering high efficiency in a 6 -lead ThinSOT package. Capable of supplying 5V at 800mA from a Lithium Battery input, the devices contain an internal NMOS switch and PMOS synchronous rectifier.A switching frequency of 1.5MHz minimizes solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. The current mode PWM design is internally compensated, reducing external parts count. The CXSU63033A features automatic shifting to power saving PFM Mode operation at light loads. Antiringing control circuitry reduces EMI concerns by damping the inductor in discontinuous mode, and the devices feature low shutdown current of under 1μA.Both devices are available in the low profile (1mm) SOT-23 package.产品特点 返回TOP Up to 93% Efficiency 1.5MHz Fixed Frequency Switching Internal Synchronous Rectifier 2.5V to 5V Output Range Automatic PFM/PWM Mode Operation Logic Controlled Shutdown (<1μA) Antiringing Control Minimizes EMI Tiny External Components Low Profile (1mm) SOT-23 Package 应用范围 返回TOP MP3/4 PMP Digital Camera LCD Bias Voltage Handheld Instruments Wireless Handsets GPS Receivers 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!
