PMICs – LED DriversLED drivers are a type of power management integrated circuit (PMIC) designed to control and regulate the current and voltage sent to an LED. LEDs are typically driven by varying a current pulse across its terminals since this type of power delivery yields the most consistent brightness and long-term efficiency. LED drivers vary the current with algorithm-based settings to produce the desired luminance, allowing the LED to be used in many applications such as general lighting, backlighting, signage, automotive lighting, and others. One of the most popular type of LED drivers available in market is the MP4033GSE, produced by Monolithic Power Systems, Inc. The MP4033GSE is a highly integrated, high-efficiency, and easy-to-use LED driver IC specifically designed for use in LED lighting applications. It is available in a 4x4mm 32-pin TQFN package and operates from a wide input voltage range of 4.5V to 42V, making it universally compatible for applications worldwide.The MP4033GSE has several features that make it an attractive option for LED lighting applications. The device features an internal 800V power MOSFET, automatic deglitching for Dynamic Adjust & Store (DAS), secondary side adjustable current control, as well as a quasiresonant operating mode that enables high power factor and low no-load power consumption. Additional features include programming via external pin or initialization sequence, compact form factor, and excellent thermal performance. Furthermore, the device is equipped with various protection functions, such as out-of-regulation protection, over-temperature protection, and over-current protection.The MP4033GSE is capable of driving a maximum load current of 50mA per channel with typical power efficiency of up to 90%. Depending on the application, the device can be operated in a primary side control mode or secondary side control (dimming) mode. In a primary side control mode, the device utilizes a peak current of PFC circuit to regulate the LED current to maintain a constant current. Theykey feature of this mode is that it eliminates any additional component cost or secondary side control circuitry as external LED current sensing is not required.On the other hand, in a secondary side control mode, the MP4033GSE utilizes a converter to accurately sense and regulate the LED current in case of a mismatch between the LEDs. In this mode, the device is compatible with a wide range of dimming algorithms such as PWM, DC voltage, and Resistance dimming.The MP4033GSE is suitable for a wide range of LED lighting applications, including but not limited to indoor lighting, die-casting and street lighting, automotive lighting, and backlighting. The device is capable of efficient power conversion over a wide input voltage range of 4.5V to 42V and provides excellent thermal management for a longer lifetime for the LED. In conclusion, the MP4033GSE is a versatile, integrated, easy-to-use LED driver IC from Monolithic Power Systems, Inc., that offers high efficiency, excellent thermal performance and a wide range of protection functions in a small form factor for use in a variety of LED lighting applications.
