AL8807
HIGH EFFICIENCY LOW EMI 30V 1A BUCK LED DRIVER
Applications Information
(cont.)
An inductor choice of 33µH with saturation current higher than 1.1A, will limit the frequency variation between 180kHz and
400kHz over the whole input voltage variation (8V to 18V), and therefore represent the best choice for an MR16 solution also
taking into account the size constraint of the lamp.
The AL8807 guarantees high performance levels with both 12V
and 12V
power supplies.
AC
DC
The efficiency is generally higher than 81% and current regulation is better than 0.1mA/V in for a DC input voltage in the
range from 8V to 18V.
