   产品概述 返回TOPC0T嘉泰姆

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
