产品概述 返回TOPqQT嘉泰姆
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. The CXLE8166 is available in TDFN2x2-6
package.
