目录7.相关产品 产品概述 返回TOP CXSD62371 is a 6A, synchronous DC/DC buck converter with integrated 30mΩ N-channel high-side MOSFET and 15mΩ N-channel low-side MOSFET. It 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 CXSD62371 achieves high efficiency at a reduced cost by eliminating the current-sense resistor found in traditional current-mode PWMs. Single-stage buck conversion allows these devices to directly step down high-voltage batteries for the highest possible efficiency. The GCXSD62371is intended for the power supply of Notebook Computer, or other low-voltage supplies as low as 0.75V. The GCXSD62371is available in QFN3X3-24 package.产品特点 返回TOP „ Ultra-High Efficiency „ Low Quiescent Current of 40μA „ Integrated 15mΩ at VCC=5V N-Channel MOSFET for Low Side „ Integrated 30mΩ at VCC=5V N-Channel MOSFET for High Side „ No Current-Sense Resistor (Lossless ILIMIT) „ Quasi-PWM with 100ns Load-Step Response „ 1% VOUT Accuracy Over Line and Load „ Programmable Switching Frequency „ 0.75V to 3.6V Adjustable Output Range „ 3V to 28V Adapter or Battery Input Range „ Integrated Boost Switch „ OVP & UVP „ Over Temperature Protection (non-latch) „ 2ms Soft-Start „ Power-Good Indicator 应用范围 返回TOP „ Notebook Computers „ I/O Supply „ Chipset/RAM Supply as Low as 0.75V „ Networking Power Supply 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!
