CXSU63170是一个电流模式和固定频率升压转换器,集成了N-FET来驱动白色LED。串联允许LED电流相同,亮度均匀。它的低导通电阻和低反馈电压降低了功率损耗,实现了高效率。快速开关频率(典型为1.5MHz)允许使用小尺寸电感以及输入和输出电容器。过电压保护功能通过OVP引脚监测输出电压,如果OVP电压超过过电压阈值,则停止IC的切换。内部软启动电路消除启动过程中的浪涌电流。

The CXSU63170 is a current-mode and fixed frequency boost converter with an integrated N-FET to drive white LEDs. The series connection allows the LED current to be identical for uniform brightness. Its low on-resistance of NFET and low feedback voltage reduce power loss and achieve high efficiency. Fast switching frequency(1.5MHz typical) allows using small-size inductor and both of input and output capacitors. An over voltage protection function,which monitors the output voltage via OVP pin, stops switching of the IC if the OVP voltage exceeds the over voltage threshold. An internal soft-start circuit eliminates the inrush current during start-up. The CXSU63170 also integrates under-voltage lockout, overtemperature protection, and current limit circuits to protect the IC in abnormal conditions. The CXSU63170 is available in a SOT-23-6A
