MP4021AGS-Z is a 4-channel PMIC - LED drivers that offers maximum flexibility across a variety of applications. It is capable of driving up to four channels of LEDs with one MP4021AGS-Z device, providing a reliable and cost-effective solution for multiple applications. The MP4021AGS-Z can be configured to operate in either constant current or constant voltage mode, and features a wide Input Voltage Operating Range of 3 V to 15 V. It also includes an over-temperature protection circuit and a low output voltage sense circuit to ensure safe operation.

The MP4021AGS-Z can be used in a myriad of applications, such as general lighting products, automotive external lighting, home appliance applications, and even commercial displays. The MP4021AGS-Z is particularly well-suited for use in low profile and thermally constrained applications, due to its low profile 3 mm AHP8 package, high switching speed and low quiescent current. In addition, the available LED voltages, input voltage operating range and output current setting range of the MP4021AGS-Z provide great design flexibility, allowing the user to customize each application’s functionality.

The working principle of the MP4021AGS-Z is quite simple. Its main components are a power FET, a driver circuit and a reference voltage circuit. When a current is input to the MP4021AGS-Z, the power FET switches on and off to regulate the output current. The driver circuit amplifies and adjusts the signal, and the reference voltage circuit maintains the LED voltage at a constant level. This keeps the LED current at a controlled level and ensures a stable output.

The MP4021AGS-Z is an excellent choice for LED driving applications due to its simple working principle and wide range of features and applications. Its low profile package and low output voltage sense ensures safe operation and reliable performance, while its inherent flexibility makes it ideal for a multitude of applications. It is a cost-effective and reliable solution that is becoming increasingly popular in the LED driving market.
