MP4020 Primary Side Control Offline LED Controller With PFC and TRIAC Dimming The Future of Analog IC Technology PRELIMINARY SPECIFICATIONS SUBJECT TO CHANGE 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.

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. www.MonolithicPower.com MPS Proprietary Information.
