The CXLE8160 is a current-mode and fixed frequency boost converter with an integrated N-FET to drive up to 10 white LEDs in series.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(1MHz 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 CXLE8160 also integrates under-voltage lockout, overtemperature protection, and current limit circuits to protect the IC in abnormal conditions
