MP3398AGS

MP3398AGS is a high-level PMIC (Power Management IC) LED driver, developed by Monolithic Inc. This device combines the controller and the power MOSFET in a single package, which not only increases the efficiency but also simplifies the design. The MP3398AGS is designed to drive LED that require high current and high voltage, while maintaining a wide input voltage range. It is suitable for a wide range of applications including LED lighting, LED signages and automotive applications.

The MP3398AGS consists of an active controlled MOSFET and a sense resistor. The device has an adjustable output voltage and current that can be adjusted by the user through an internal control signal. The device also has adjustable hysteresis, soft-start, and protection functions. The on-board temperature monitor feature helps keep the operating temperature in check for safe operation.

The MP3398AGS is ideal for applications requiring current and voltage regulation. For example, it can be used in LED lightings and signages, where it can provide precise regulated current and voltage to enable the exact brightness of the LEDs. In addition, MP3398AGS can be used in automotive applications like rear lights and fog lamps to ensure precise current and voltage delivery.

MP3398AGS is designed to provide superior performance with low power consumption and high efficiency. The device’s MOSFET is integrated with a PWM controlling circuit to regulate the LED current. The PWM signal is generated by an internal current regulator, which senses the LED current and output an adjustable PWM signal based on the user’s setting. The PWM signal is used to control the gate of the MOSFET and in turn regulate the LED current.

The device also features a gate voltage regulations function to ensure the MOSFET is always operated in its optimal parameters. This feature helps prolong the MOSFET’s life by preventing it from overheating or over-current conditions. Other features of MP3398AGS include over-current protection and over-temperature protection.

In conclusion, MP3398AGS is a high performance PMIC LED driver that provides precise regulation of current and voltage for LED applications. It is suitable for a wide range of applications including LED lightings, LED signages and automotive applications. With its low power consumption, high efficiency and integrated protection functions, it is an excellent choice for any application requiring high precision current and voltage regulation.
