目录7.相关产品 产品概述 返回TOP The CXSU63229 is a wide input voltage (4.5V to 27V), non-synchronous boost controller. It is suitable for topologies including boost, flyback, SEPIC and various LED Driver applications which require a grounded source N-channel FET. The device features include programmable soft start, over current protection with automatic retry, programmable oscillator frequency and integrated Low-side driver. Current mode control provides improved transient response and simplified loop compensation.产品特点 返回TOP „ Input Voltage: 4.5V to 27V „ Adjustable Oscillator Frequency „ Fixed Frequency Current Mode Control „ Integrated Low-Side Driver „ Programmable Soft Start „ Over Current Protection „ Reference 700mV „ Low Power Shutdown Function 应用范围 返回TOP „ LED Lighting „ Industrial Control Systems „ Battery Powered Systems 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
