MP4021 LED DRIVER
Mp4021 led Proprietary Information. Patent Protected. This signal provides the reference for the current comparator and comparing with the primary side inductor current which sets the primary peak current shaped as sinusoid with the input line voltage. High power factor can be achieved.
Primary Side Control Offline LED Controller with Active PFC
Multiplier output on, if ZCD fails mp4021 led send mp4021 led another turn on signal after ? Minimum Off Time The MP operates with variable switching frequency, the frequency is changing with the input instantaneous line voltage.

It also limits primary-side turn-on switching loss using boundary conduction mode BCM and implements mp4021 led power-factor correction PFC. The MP's primary-side control solution relies on a proprietary real-current control method to accurately estimate the current through the transformer's secondary side without additional circuitry.
This method uses a sense resistor connected to the MOSFET to measure the current through the transformer's primary-side, as shown in Figure 1. No Preview Mp4021 led Top Marking.
MPGS—Z. Mp4021 led current can be accurately controlled with the real current control method form the primary side information.
Then the power supply is taken over by the auxiliary winding. When the external Mp4021 led turns off, the energy stored in the inductor forces the secondary side diode to be turn-on, and the current of the inductor begins mp4021 led decrease linearly from the peak value to zero.

When the current decreases mp4021 led zero, the parasitic resonant of inductor and all the parasitic capacitance makes the MOSFET drain-source voltage decrease, this decreasing is also reflected on the auxiliary winding see Figure 2. However, LED penetration in general mp4021 led, especially residential lighting, has met with significant resistance.
Part of the difficulty mp4021 led from the development of a cost-effective method of adapting a DC device to run using the AC mains signal—which typically requires more circuitry than incandescent bulbs. This circuitry can contribute significantly to the cost of LED luminaires while eating into the expected energy savings and luminous output that remains among the biggest issues to limit market penetration.
