198VAC~265VAC/50Hz, 24V/420mA
Primary-side-control with Active PFC
Off-line Dimmable LED Driver Evaluation Board
The Future of Analog IC Technology
DESCRIPTION
FEATURES
The EV4033-K-00A Evaluation Board is
designed to demonstrate the capabilities of
MP4033 with ripple suppressor. The MP4033 is
a primary-side-control offline LED lighting
controller which can achieve high power factor
and accurate current for Triac dimmable LED
lighting application. Its adaptive dimmer type
detection and phase-cut-based dimming control
can achieve good dimmer compatibility and
deep dimming range.
•
•
It works in boundary conduction mode for
reducing the MOSFET and Diode switching
losses. The new ripple suppressor can
obviously reduce the output current ripple and
escape the flicker or shimmer happened in
deep dimming situation with a little influence in
efficiency.
The EV4033-K-00A is typically designed for
driving a 10W Triac dimmable LED bulb with
24VTYP, 420mA LED load from 198VAC to
265VAC, 50Hz.
The EV4033-K-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; winding short circuit protection;
output short-circuit protection, cycle by cycle
current limit, etc.

EV4033-K-00A – HIGH LINE VOLTAGE, 10W PSR WITH PFC DIMMABLE LED DRIVER
CIRCUIT DESCRIPTION
The EV4033-K-00A is configured in a singlestage Flyback topology; it uses primary-sidecontrol which can mostly simplify the schematic
and get a cost effective BOM. It can also achieve
high power factor and accurate LED current.
F1, RV1, L1, L2, L3, L4, R1, R2, R5, CX1, BD1,
C4 and C3 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, L2, L3, L4, R1, R2, R5, CX1, C3
and C4 associated with CY1 form the EMI filter
which can meet the standard EN55015. The
diode rectifier BD1 rectifies the input line voltage.
Small bulk CBB capacitor C3 is used for a low
impedance path for the primary switching current,
to maintain high power factor, the capacitance of
C3 should be selected with low value.
R6, Q1 with C2 compose the damping circuit for
reducing the inrush current at the dimmer turning
on time. The circuit let the inrush current flow
through R6 at first when triac dimmer turns on.
Then Q1 turns on and shorts R6, this can save
power from R6.
R4, R3, C1 are used as a bleeder circuit which
keeping the triac current above the minimum
holding current after triac turns on.
R8, R7, C5 provide sine wave reference for the
primary peak current to get an active PFC
function. The divided voltage should be lower
than the max voltage rating of MULT pin.
R9, D1, C6 and D2 are used to supply the power
for MP4033. A 22μF bulk capacitor C6 is
selected to maintain the supply voltage. At
start-up, C6 is first charged up through the
external MOSFET Q2 and internal charging
circuit, when the VCC voltage reaches 10V, the
internal charging circuit stops charging. Then the
power supply is taken over by the auxiliary
winding through R9, D2.
R10, C7, R19, D3 and D7 are used for the gate
drive of the external MOSFET Q2.
R15, R14 and D5 are used to detect the auxiliary
winding to get the transformer magnetizing
current zero crossing signal for realizing the
boundary conduction operation, and also monitor
the output OVP condition. The OVP voltage is set
by the divider ratio of R15 and R14.
R12, R13 are primary sensing resistors for
primary side current control. The value of R12,
R13 set the output LED current. C9, R11, D4 are
used to damp the leakage inductance energy so
the drain voltage can be suppressed at a safe
level.
Diode D6 rectifies the secondary winding voltage
and the capacitor C10, C11 are the output filter.
The resistor R22 is placed as pre-load to limit the
output voltage rise too high in open load
condition.
R16, R17, R18, R20, R21, C12, D8, D9, D10,
D11, D12, C13 and Q3 compose the ripple
suppressor. R17, R18 and C13 offer a stable
drive voltage to Q3. D8 and D9 compose the fast
start up circuit, which help charge C13 quickly at
the moment power on. D10, R21, R20, C12, D12
and R17 add a bias voltage to the gate of Q3,
which will help save the power loss of the ripple
suppressor obviously.

EV4033-K-00A – HIGH LINE VOLTAGE, 10W PSR WITH PFC DIMMABLE LED DRIVER
Electric Strength Test
Primary circuit to secondary circuit electric strength testing was completed according to IEC61347-1
and IEC61347-2-13.
Input and output was shorted respectively. 3750VAC/50Hz sine wave applied between input and output
for 1min, and operation was verified.
Surge Test
Line to Line 500V and Line to Power Earth 1kV surge testing was completed according to IEC61547.
Input voltage was set at 230VAC/50Hz. Output was loaded at full load and operation was verified
following each surge event.

QUICK START GUIDE
1. Preset AC Power Supply to 198VAC ≤ VIN ≤265VAC.
2. Turn Power Supply off.
3. Connect the LED string between “LED+” (anode of LED string) and “LED-” (cathode of LED string).
4. Connect Power Supply terminals to AC VIN terminals as shown on the board.
5. Turn AC Power Supply on after making connections.
