DESCRIPTION
FEATURES
The EV4068-N-00A Evaluation Board is
designed to demonstrate the capabilities of
MP4068. The MP4068 is a highly integrated
TRIAC dimmable LED driver with high power
factor. It is specifically designed for low-line
input (120VAC), no-isolated, TRIAC-dimmable
LED lighting applications, especially for the low
cost and small form factor applications.

The integrated 500V MOSFET ensures the
system to withstand 500V surge test without
MOV or TVS. Only a single winding inductor is
required to realize the solution. It features
MPS’s proprietary hybrid operation mode which
is designed to achieve good dimming
performance.
The EV4068-N-00A is typically designed for
driving an 8W TRIAC dimmable LED bulb with
50VTYP, 160mA LED load from 108VAC to
132VAC, 60Hz.
The EV4068-N-00A has an excellent efficiency
and meets IEC61547 surge immunity,
IEC61000-3-2 Class C harmonics and
EN55015 conducted EMI requirements. It has
multi-protection function as over-voltage
protection; output short-circuit protection,
thermal shut down, etc.

EV4068-N-00A – LOW LINE VOLTAGE, 8W LOW COST DIMMABLE LED DRIVER
CIRCUIT DESCRIPTION
The EV4068-N-00A is configured in a singlestage Buck topology and gets a cost effective
BOM. It also achieves high power factor and
excellent TRIAC dimming performance.
power may not be enough supplied only by the
high voltage regulator, the diode D2 connected to
output will help maintain the power supply
voltage .
FR1, RV1, L1, R7, C2, and BD1 compose the
input stage. The fusible resistor FR1 fuses the
AC input to protect for the component failure or
some excessive short events, its resistance is
also used as a passive damper of dimming. RV1
is used for surge test. L1, R7 and C2 associated
with C3 form an EMI filter. The diode rectifier
BD1 rectifies the input line voltage.
R1 and R2 are used to monitor the output OVP
condition. The OVP voltage is set by the divider
ratio of R1 and R2.
R5, C5 are used as a bleeder circuit which
keeping the TRIAC current above the minimum
holding current after TRIAC turns on.
R4, D2, C1 and C6 are used to supply the power
for MP4068. At normal work, the power is
charged by the internal high voltage regulator
from HV pin. But in deep dimming condition, the
R3, R8 are sensing resistors for LED current
control. The value of R3 and R8 set the output
LED current.
Diode D1 is the Buck fly-wheel diode, the
inductor L2 and the capacitor C4 are the output
filter. The resistor R6 is placed as a dummy load
to consume the output power in open load
condition. The diode D3 is used to prevent the
output current flowing back to IC when input Sine
voltage drops lower than output voltage.
