产品概述 返回TOPgOk嘉泰姆
The CXLE8159 is a current-mode and fixed frequency
boost converter with an integrated N-FET to drive up to 6
white LEDs in series.The series connection allows the LED current to be identical
for uniform brightness. Its low on-resistance of NFET
and feedback voltage reduces power loss and
achieves high efficiency. Fast 1MHz current-mode PWM
operation is available for input and output capacitors and
a small inductor while minimizing ripple on the input
supply. The OVP pin monitors the output voltage and stops
switching if exceeds the over-voltage threshold. An internal
soft-start circuit eliminates the inrush current during
start-up.
The CXLE8159 also integrates under-voltage lockout,
over-temperature protection and current limit circuits.
The CXLE8159 is available in SOT-23-6 and TSOT-23-6
packages
