CIRCUIT DESCRIPTION
The EV4068-S-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.
F1, RV1, L1, R7, C2, and BD1 compose the input
stage. F1 fuses the AC input to protect for the
component failure or some excessive short
events. RV1 is used for surge test. L1, R7 and
C2 form an EMI filter. The diode rectifier BD1
rectifies the input line voltage.
C7, L3 and C3 form a π structure EMI. R12, C8
are used as a bleeder circuit which keeping the
TRIAC current above the minimum holding
current after TRIAC turns on.

R3, R11 are sensing resistors for LED current
control. The value of R3 and R11 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.
C
T
O
A
I
R1 and R2 are used to monitor the output OVP
condition. The OVP voltage is set by the divider
ratio of R1 and R2.
D
I
R8, R9, R10, R5, Q1 with C5 compose the active
damping circuit. It helps to reduce the inrush
current through dimmer at the moment dimmer
turning on. The circuit let the inrush current flow
through R5 at the moment TRIAC dimmer turning
on. Then Q1 turns on and shorts R5, this saves
power loss from R5. The R10 connected from
bus provides a bias voltage for the gate driver of
Q1, which also save power loss of Q1.
N
O
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
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.

I
1. Preset AC Power Supply to 108VAC ≤ VIN ≤132VAC.
2. Turn Power Supply off.
3. Connect the LED string between “LED+” (anode of LED string) and “LED-” (cathode of LED string).
T
4. Connect Power Supply terminals to AC VIN terminals (“L” and “N”) as shown on the board.
5. Turn AC Power Supply on after making connections.
