目录7.相关产品 产品概述 返回TOP The CXSD62398 is a flexible asynchronous buck controller with a built in 200mA driver for P-channel FETs. The input voltage is up to 27V. The CXSD62398 operates with voltage-mode feedback and has feed-forward input-voltage compensation that responds instantly to input voltage change. The internal 700mV reference is trimmed to 1%, giving accurate output voltages. Clock frequency, soft-start, and overcurrent limit are each easily programmed by a single, external component. Over voltage protection (OVP) can be adjusted by setting the external resistors. Input under-voltage lockout is implemented. The CXSD62398 is available in 10-pin MSOP exposed pad package.产品特点 返回TOP „ Input Voltage: 4.5V to 27V „ Output Voltage (700mV to 90% VIN) „ 200mA Internal P-Channel FET Driver „ Voltage Feed-Forward Compensation „ Undervoltage Lockout „ Hiccup Overcurrent Fault Recovery „ Programmable Fixed Frequency (35~500KHz) Operation „ Programmable Short Circuit Protection „ 700 mV 1% Reference Voltage „ Programmable Closed Loop Soft Start „ Disable Function Available „ Programmable Over-Voltage Protection „ MSOP-10 with Exposed Pad Package Available 应用范围 返回TOP „ Telecom „ DSL/Cable Modems „ Scanners „ Power Applications 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
