The CXLE8166 is a current-mode and fixed frequency 600kHz 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. 600kHz Constant switching frequency allows using small-size inductor and both of input and output capacitors. An over voltage protection function, which monitors the output voltage via LX pin, stops switching of the IC if the LX voltage exceeds the over voltage threshold. An internal soft-start circuit eliminates the inrush current during start-up. The CXLE8166 also integrates under-voltage lockout and over-temperature protection to protect the IC in abnormal conditions
