Working Principle

MP4050AGJ-P is based on a synchronous boost (step-up) topology. It uses an internal power MOSFET as the switching element and an internal voltage sensing circuitry to effectively regulate current and output voltage. The internal power MOSFET is designed to reduce the overall system cost by eliminating the need for an external power switch. It also ensures high efficiency, low ripple and minimal noise.

The MP4050AGJ-P is a wide input range, high current LED driver with true dimming capability. It features an integrated power switch and current sense resistor. The switch can be used to turn on and off the LED driver and the current sense resistor to regulate the LED current flow. Output voltage accuracy is maintained between 0.8 % to a maximum of 24V.

The MP4050AGJ-P integrates user-defined dimming methods of operation, including direct current mode (DCM), Phase-Cut Dimming (PCD) mode, and Pulse-Width Dimming (PWM) mode. DCM is a low cost, low ripple, low power mode of operation. PCD is a highly efficient and EMF immune dimming method used to control brightness. PWM dimming is used to provide very low dimming levels.

Conclusion

The MP4050AGJ-P is a highly efficient, low-cost, and flexible power management IC suitable for a variety of applications. It operates in a wide input voltage range and provides several protection features such as over-current protection, over-voltage protection, and a variety of user-defined dimming methods. the MP4050AGJ-P is an ideal choice for LED lighting applications.
