Primary-Side-Controlled,
Offline, LED Driver Evaluation Board
DESCRIPTION
FEATURES
The
EV4034-S-00B
Evaluation
Board
demonstrates the capabilities of the MP4034: a
primary-side-controlled, offline, LED lighting
controller that eliminates secondary feedback
components.
•
The EV4034-S-00B typically drives a 3.5W LED
string with a 10VTYP, 350mA LED load from
85VAC to 265VAC at 50Hz.
The EV4034-S-00B has excellent efficiency and
meets IEC61547 surge immunity and EN55015conducted EMI requirements. It has multiple
protections, including open-circuit protection,
short-circuit protection, a cycle-by-cycle current
limit, and over-temperature protection.

CIRCUIT DESCRIPTION
The EV4034-S-00B is configured for a singlestage, flyback topology. It uses primary-sidecontrol to simplify the schematic and reduce
BOM costs. It can also achieve an accurate LED
current.
The input stage consists of FR1 and DB1. FR1
protects against component failure or some
excessive short events, and can restrain the
inrush current.
CY1 is a Y capacitor that lowers common-mode
noise to ensure a sufficient EMI margin. T1 is the
power transformer, the structure of which is also
very important to pass EMI test.
D3, C5, and R7 compose output circuit. D3 is a
Schottky diode for better efficiency. C5 is a
ceramic capacitor for lower output-voltage ripple
and R7 is the dummy load for open-lamp
protection.
The π filter (C1, L1, and C2) guarantees that the
conducted EMI meets the EN55015 standard.
The snubber circuit (R2, R3, D1, and C3)
reduces the drain-source voltage spike.
R4, C4, and D2 provide the VCC power supply.
The resistor divider (R5 and R6) provides openlamp protection by sampling the voltage on the
primary auxiliary winding. When an open occurs,
the output voltage remains constant.
