MP4030A
TRIAC-Dimmable, Primary-Side-Control
Offline LED Controller with Active PFC
DESCRIPTION
The MP4030A is a TRIAC-dimmable, primary-
side-control, offline LED lighting controller with
active PFC. It can output an accurate LED
current for an isolated lighting application with a
single-stage converter. The proprietary real-
current-control method can accurately control the
LED current using primary-side information. It
can significantly simplify LED lighting system
design by eliminating secondary-side feedback
components and the optocoupler.
The MP4030A implements power-factor
correction and works in boundary-conduction
mode to reduce MOSFET switching losses.
The MP4030A has an integrated charging circuit
at the supply pin for fast start-up without a
perceptible delay.
The proprietary dimming control expands the
TRIAC-based dimming range.
The MP4030A features multiple protections
including over-voltage protection (OVP), short-
circuit protection (SCP), primary-side over-
current protection (OCP), supply-pin under-
voltage lockout (UVLO), and over temperature
protection (OTP). All of which not only simplifies
circuit design but also enhances system reliability
and safety greatly. All fault protections feature
auto-restart.
The MP4030A is available in an 8-pin SOIC
package.

ABSOLUTE MAXIMUM RATINGS (1)
VCC Pin Voltage ...........................-0.3V to +30V
Low-Side MOSFET Drain Voltage -0.3V to +30V
ZCD Pin Voltage ................................-8V to +7V
Other Analog Inputs and Outputs .....-0.3V to 7V
ZCD Pin Current ..........................-5mA to +5mA
Continuous Power Dissipation (TA = +25°C) (2)
SOIC8 ........................................................ 1.3W
Junction Temperature ...............................150°C

Storage Temperature............... -65°C to +150°C
Recommended Operating Conditions (3)
Thermal Resistance (4) θJA θJC
SOIC8 ....................................96 ...... 45 ... °C/W
Notes:
1) Exceeding these ratings may damage the device.
2) The maximum allowable power dissipation is a function of the
maximum junction temperature TJ(MAX), the junction-to-
ambient thermal resistance θJA, and the ambient temperature
TA. The maximum allowable continuous power dissipation at
any ambient temperature is calculated by PD(MAX)=(TJ(MAX)-
TA)/ θJA. Exceeding the maximum allowable power dissipation
will cause excessive die temperature, and the regulator will go
into thermal shutdown. Internal thermal shutdown circuitry
protects the device from permanent damage.
3) The device is not guaranteed to function outside of its
operation conditions.
4) Measured on JESD51-7 4-layer board.
VCC Pin Voltage ...............................11V to 27V
Operating Junction Temp (TJ).. -40°C to +125°C

Pin Function
Internal Multiplier Input. Connect to the tap of resistor divider from the rectified voltage of
the AC line. The half-wave sinusoidal signal provides a reference signal for the internal
current-control loop. MULT also detects the TRIAC-dimming phase.
Zero-Current Detection. A negative going-edge triggers the internal MOSFET’s turn-on
signal. Connect to the tap of a resistor divider from the auxiliary winding to GND. The ZCD
pin can also detect over-voltage. Over-voltage occurs if VZCD exceeds the OVP threshold
after a 1.85µs blanking time when the internal MOSFET turns off.
Supply Voltage. Supplies power for both the control signal and the internal MOSFET’s gate
driver. Connect to an external bulk capacitor - typically 22µF with a 100pF ceramic capacitor
to reduce noise.
Dimming Pull-Down. Drain of the internal dimming pull-down MOSFET. Connect a resistor
from this pin to the D pin to pull down the rectified input voltage during the TRIAC dimming
OFF interval.
Internal Low-Side Main MOSFET Source. Connect a resistor from this pin to GND to sense
the internal MOSFET current. An internal comparator compares the resulting voltage to the
internal sinusoid shaped current reference signal to determine when the MOSFET turns off.
If the voltage exceeds the current-limit threshold of 2.3V after the leading edge blanking
time during the turn-on interval, the gate signal turns off. Over-current occurs if Vs exceeds
2.73V during the turn-on interval after the leading-edge blanking time for OCP.
Internal Low-Side Main MOSFET Drain. Internally connects to VCC via a diode and a JFET
to form an internal charging circuit for VCC. Connect to the source of the high-side MOSFET.
An internal MOSFET pulls up the D to VCC through a diode at fault condition to turn off the
main switch.
Ground. Current return of the control signal and the gate drive signal.
Loop Compensation. Connects to a compensation network to stabilize the LED driver and
accurately control the LED driver current.
