DESCRIPTION
The EV4026-J-00C Evaluation Board is
designed to demonstrate the capabilities of
MP4026. The MP4026 is a primary-side-control
offline LED lighting controller which can achieve
high power factor and accurate LED current for
an isolated lighting application in a single stage
converter. It works in boundary conduction
mode for reducing the MOSFET and Diode
switching losses.
The EV4026-J-00C is typically designed for
driving an isolated 18W T8 LED lamp with
36V
TYP
, 500mA LED load at universal input
(90V-265VAC, 50/60Hz).
The EV4026-J-00C has high performances in
efficiency, line/load regulation and meets
IEC61547 surges, IEC61000-3-2 Class C
harmonics and EN55015 conducted EMI. It has
multi-protection function as over-voltage
protection, short-circuit protection, primary-side
OCP, etc.
