1 Description
The MG39113 is a high precision linear LED driver. The current is programmable
through an external resister. The maximum delivery current is 150mA. The driving scheme can
be configured as one tap or multi tap structure.
If the LED string is configured into multi segments, each segment is sequentially turned
on and off by tracking the on/off state of others segments. Since voltage applied on IC is
minimized when conducting, the lighting efficiency is high. The AC voltage and line ‐input
current could be tuned in phase, so high PF is possible.
The LED strings can be configured with different structures: one tap, multi-taps and two
taps with equivalent light output. Also the IC can be placed in parallel for high wattage output.
The device is available in SOT89 package or dice form.
