目录7.相关产品 产品概述 返回TOP CXSD62362A/CXSD62362B PWM 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 CXSD62362A/CXSD62362 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. Single-stage buck conversion allows these devices to directly step down high-voltage batteries for the highest possible efficiency. Alternatively, two-stage conversion (stepping down the +5V system supply instead of the battery) at a higher switching frequency allows the minimum possible physical size. The CXSD62362/CXSD62362 is intended for CPU core, chipset, DRAM, or other low-voltage supplies as low as 0.75V. It provides four resistor-programmable output voltages by G0 and G1 digital inputs. The CXSD62362/CXSD62362 is available in 16-pin TQFN (3X3) package.产品特点 返回TOP „ Ultra-High Efficiency „ No Current-Sense Resistor (Lossless ILIMIT) „ Quasi-PWM with 100ns Load-Step Response „ 1% VOUT Accuracy Over Line and Load „ 0.75V to 3.6V Adjustable Output Range „ Dynamic Voltage Scaling by G0 and G1 Inputs „ 4.5V to 24V Battery Input Range „ OVP & UVP „ Built-in BST Diode „ 1.7ms Soft-Start „ Drives Large Synchronous-Rectifier FETs „ Power-Good Indicator „ G0/G1 High Active (CXSD62362A) G0/G1 Low Active (CXSD62362B) 应用范围 返回TOP „ Notebook Computers „ CPU Core Supply „ Chipset/RAM Supply as Low as 0.75V „ 1.8V and 2.5V I/O Supply „ 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！ 产品封装图 返回TOP
