MP4030A TRIAC-Dimmable, Primary-Side-Control Offline LED Controller with Active PFC The Future of Analog IC Technology DESCRIPTION The MP4030A is a TRIAC-dimmable, primaryside-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 realcurrent-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), shortcircuit protection (SCP), primary-side overcurrent protection (OCP), supply-pin undervoltage 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 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.

Optional Protection Circuit In large output voltage or large LEDs current application, MOSFET M may be destroyed by over-voltage or over-current when LED+ shorted to LED- at working. Gate-Source (GS) Over-voltage Protection: DO NS D RO + R M DG DZ RG CO C + Figure 15: Gate-Source OVP Circuit Figure14: Ripple Suppressor Principle: Shown in Figure 14, Resister R, capacitor C, and MOSFET M compose the ripple suppressor. Through the RC filter, C gets the mean value of the output voltage VCo to drive the MOSFET M. M works in variable resistance area. C’s voltage VC is steady makes the LEDs voltage is steady, so the LEDs current will be smooth. MOSFET M holds the ripple voltage vCo of the output. Diode D and Zener diode DZ are used to restrain the overshoot at start-up. In the start-up process, through D and DZ, C is charged up quickly to turn on M, so the LED current can be built quickly. When VC rising up to about the steady value, D and DZ turn off, and C combines R as the filter to get the mean voltage drop of VCo. The most important parameter of MOSFET M is the threshold voltage Vth which decides the power loss of the ripple suppressor. Lower Vth is better if the MOSFET can work in variable resistance area. The BV of the MOSFET can be selected as double as VCo and the Continues Drain current level can be selected as decuple as the LEDs’ current at least. Figure 15 shows GS over-voltage protection circuit. Zener diode DG and resistor RG are used to protect MOSFET M from GS over-voltage damaged. When LED+ shorted to LED- at normal operation, the voltage drop on capacitor C is high, and the voltage drop on Gate-Source is the same as capacitor C. The Zener diode DG limits the voltage VGS and RG limits the charging current to protect DG. RG also can limit the current of DZ at the moment when LED+ shorted to LED-. VDG should bigger than Vth. Drain-Source Over-voltage and Over-current Protection As Figure 16 shows, NPN transistor T, resistor RC and RE are set up to protect MOSFET M from over-current damaged when output short occurs at normal operation. When LED+ shorted to LED-, the voltage vDS of MOSFET is equal to the vCo which has a high surge caused by the parasitic parameter. Zener Dioder DDS protects MOSFET from over-voltage damaged. Transistor T is used to pull down the VGS of M. When M turns off, the load is opened, MP4030A detects there is an OVP happened, so the IC functions in quiescent.
