目录7.相关产品 产品概述 返回TOP The CXSU63235 boost converter in corporate high-performance, current-mode, frequency selectable pulse width modulation (PWM) circuitry with a built-in 0.2Ω n-channel MOSFET to provide a highly efficient regulator. High switching frequency allows easy filtering and faster loop performance. An external compensation pin provides the user flexibility in determining loop dynamics, allowing the use of small, low ESR ceramic output capacitors. The device can produce an output voltage as high as 20V. User programmed soft-start with an external capacitor determines the input current ramp rate. The CXSU63235 is available in a space-saving MSOP-8 and TDFN3X3-8 package.产品特点 返回TOP „ 90% Efficiency „ Adjustable Output from VIN to 20V „ 0.2Ω, 24V Power MOSFET „ Cycle-by-Cycle 2A Current Limit „ 2.5V to 5.5V Input Range „ 600kHz/1.2MHz Switching Frequency „ MSOP-8, TDFN3X3-8 Package 应用范围 返回TOP „ LCD Displays „ Portable Applications „ Hand-Held Devices 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
