目录7.相关产品 产品概述 返回TOP The CXSU63236 boost converter incorporate high-performance, current-mode, and frequency selectable pulse width modulation (PWM) circuitry with a built-in N-channel MOSFET to provide a highly efficient regulator. The CXSU63236’s frequency can be selected by user to operate at either 600kHz or 1.2MHz. High switching frequency allows easily 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 current-mode architecture provides fast transient response to pulsed loads. The internal N-channel MOSFET can produce output voltage as high as 28V. User programmed soft-start with an external capacitor determines the input current ramp rate. The CXSU63236 is available in a 10-pin TDFN3X3 package产品特点 返回TOP „ 90% Efficiency „ Adjustable Output from VIN to 28V „ 4.6A, 0.1Ω, 30V Power MOSFET „ 2.5V to 5.5V Input Range „ 600kHz/1.2MHz Switching Frequency „ TDFN3X3-10 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
