目录7.相关产品 产品概述 返回TOP The CXSD6291HC family are fixed frequency, high performance, current-mode PWM controllers. Undervoltage lockout circuitry allows the CXSD6291HC to start up at 14V/8.4V and operate down to 9.8V/7.6V, operate up to 24V. The ultralow start-up current - 25μA (typ) , and operating current - 2mA (typ) charactersitics have been designed to improve the converter efficiency. High output driving capability up to 1.2A ensures the fast switching to minimize the switching losses. The CXSD6291HCfeatures a trimmed oscillator discharge current and bandgap reference. CXSD6291HC is available in both 8-pin plastic DIP and SOP packages产品特点 返回TOP • Ultralow start-up current (25μA typical) • Low operating current (2mA typical) • Fast output rise/fall times : −15ns rise/10ns fall • High output drive (1.2A peak current) • CMOS outputs with rail-to-rail swing • Current-mode operation up to 1MHz • Trimmed 5V bandgap reference • Pin-to-pin compatible with MIC38HC42/3 • Trimmed oscillator discharge current • UVLO with hysteresis • Low cross-conduction currents 应用范围 返回TOP • Current-mode , Off-line , Switched-mode Power Supplies • Current-mode , DC-to-DC converters • Various converters ( step-down , step-up , flyback , forward , and synchronous FET) 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
