PMIC – LED DriversThe MP4068GS-Z is a powerful and highly efficient LED driver integrated circuit manufactured by Mega Power Semiconductor. It is used for controlling and regulating LED lighting, backlight, and other applications such as LED strips, displays, and automotive headlamps. The MP4068GS-Z comes equipped with a wide range of features such as an adjustable current limit, an adjustable analog dimming control, fast-action short circuit protection, and various other customization options.The MP4068GS-Z has a wide input voltage range of 2.5V to 38V and a fast switching frequency of up to 100kHz, making it suitable for both DC and AC powered applications. The IC features a programmable over current protection system which allows the user to customize their current limiting parameters according to their specific need. The over current protection is triggered when the output current of the IC exceeds the programmed limit. The IC has a maximum operating temperature range of -40°C to +150°C. The IC also features internal thermal shutdown protection and open circuit protection built in to help protect the IC from potential damage from overvoltage and over current conditions.The MP4068GS-Z also has an adjustable analog dimming control input which allows the user to easily set their desired dimming level quickly and easily. The dimming level is regulated by an external resistor connected to the control pin of the IC. The dimming control input has a voltage range of 0V to 16V, which allows for precise control over the LED lighting level.The MP4068GS-Z implements average current mode control, which helps keep its output current proportional to its input voltage and helps regulate constant illumination level even when the input voltage changes. The IC also keeps its mean current constant by using its pulse-width modulation (PWM) modulation technology to adjust its duty cycle according to the input voltage. This helps ensure that the LED lighting always maintains a consistent brightness level.The MP4068GS-Z can provide up to 1.4A at a maximum output voltage of 80V. It has a maximum power dissipation of 5.5W and its switching frequency can be adjusted up to 100kHz. The IC also features an enable pin which allows the user to turn on and off the LED driver manually.The MP4068GS-Z also comes equipped with a variety of safety features including internal thermal shutdown protection which is triggered when the IC’s temperature exceeds the threshold, over current protection which helps protect the IC from dangerous currents, and open circuit protection which keeps the IC from shorting out.In conclusion, the MP4068GS-Z is a powerful LED driver which is capable of providing up to 1.4A at a maximum voltage of 80V with a maximum power dissipation of 5.5W. It has a wide input voltage range, adjustable current limiting parameters and adjustable analog dimming control inputs for precise control over the LED lighting. It also has a variety of safety features built-in for added protection.
