MPS CONFIDENTIAL AND PROPRIETARY INFORMATION- 3CEMS USE ONLY
The MP4020 is a primary-side-control offline LED
lighting controller which can achieve high power
factor and accurate LED current for an isolate
lighting application in a single stage converter.
The proprietary real current control method can
control the LED current accurately from the
primary side information. It can simplify the LED
lighting system design significantly and increase
the efficiency by removing the secondary
feedback components and the current sense
resistor.
F
The extremely low start up current and the
quiescent current can reduce the power
consumption thus lead to an excellent efficiency
performance.
N
O
The multi-protection function of MP4020 can
greatly enhance the system reliability. The
MP4020 features LED over-voltage protection,
over-current protection, VCC UVLO and overtemperature protection.

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-toambient 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.
