CXSD62360

CXSD62360通过消除传统电流模式PWMs中的电流感应电阻,以较低的成本实现了高效率。驱动超大同步整流mosfet的能力进一步提高了效率。单级降压转换允许这些设备直接降压高压电池,以获得尽可能高的效率。或者,在更高的开关频率下,两级转换(降低+5V系统电源而不是电池)允许最小的物理尺寸。

      CXSD62360 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 CXSD62360 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 CXSD62360 is intended for CPU core, chipset, DRAM, or other low-voltage supplies as low as 0.75V. The CXSD62360 is available in TSSOP-14 、 TQFN3X3-16 and TQFN3.5X3.5-14 package and includes over voltage protection.
