目录7.相关产品 产品概述 返回TOP CXSD62356 is a small-sized step-down controller uses constant on-time control scheme to handle wide input/output voltage ratios with ease and provides 100ns “instant-on” response to load transients while maintaining a relatively constant switching frequency. The CXSD62356 achieves high efficiency at a reduced cost by eliminating the current-sense resistor found in traditional current-mode PWMs. Efficiency is further enhanced by an ability to drive very large synchronous rectifier MOSFETs. The CXSD62356is intended for CPU core, chipset, DRAM, or other low-voltage supplies as low as 0.7V. The CXSD62356is available in TDFN3X3-10 package.产品特点 返回TOP „ Ultra-High Efficiency „ 4700ppm/°C RDS(ON) Current Sensing ( without Current-Sense Resistor ) „ Quasi-PWM with 100ns Load-Step Response „ Built-in 0.5% 0.7V Reference „ 0.7V to 2.6V Adjustable Output Range „ 4.5V to 28V Battery Input Range „ 4 Selectable Frequency Setting „ Integrated Boost Switch „ OVP & UVP „ 1.5ms Voltage Servo Soft-Start „ Drives Large Synchronous-Rectifier FETs „ Power-Good Indicator „ Thermal Shutdown (Non-latch) 应用范围 返回TOP „ Notebook Computers „ CPU Core Supply „ I/O Supply „ Chipset/RAM Supply as Low as 0.7V 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
