Offering superior performance for powering MR16 / AR111 lamps and general
lamp illumination applications Diodes Inc's AL8820 LED driver is now
available from Mouser stock. The LED driver is compatible with many
commonly used electronic transformers and meets high power factor (PF) and
low total harmonic distortion (THD) requirements for these applications.
The AL8820 integrates two DC-DC converters. Stage 1 is a boost PFC stage
which improves PF, reduces EMI, powers the Buck stage and the compatibility
of electronic transformers. The buck stage regulates the LED current through
the setting of an external sense resistor. The low on-resistance of the
integrated MOSFETs reduces the conduction power loss.
