PMICs, or Power Management Integrated Circuits, are a type of electronic device designed to manage, control, and regulate the power supply in an electronic system or device by adjusging, distributing, and monitoring the current, voltage, or frequency. A LED Driver is a type of PMIC specifically designed to regulate and control the current flowing to Light Emitting Diodes, or LEDs. The MXHV9910BE is a LED Driver PMIC with integrated high-voltage power switches. It is mainly used in commercial lighting applications and has numerous unique features that make it a great option for many projects.

Application Field

The MXHV9910BE is a versatile LED Driver with a wide range of commercial applications, including street lighting and architecture lighting. It is the perfect fit for projects that require high efficiency, reliable performance, and low cost. The integrated high-voltage power switches make it an ideal choice for projects that require a high-voltage input, such as those using fluorescent lamps and HID lamps. It is also suitable for outdoor lighting, as its operating temperature range of -40 to 105°C makes it suitable for use in extreme climates.

Operating Principle

The MXHV 9910BE uses an internal high-voltage power switch to regulate and control the current flowing to the LEDs. The device operates in a PWM mode, cycling the power switch at a high frequency and varying the duty cycle to adjust the output current. The current limit circuit ensures that the output current remains within a set limit, and the device also includes integrated temperature sensing functionality, ensuring that the LED current is kept within a safe temperature range.

The MXHV9910BE is equipped with an integrated ESD protection circuit that can withstand extremely high surge voltages. The device also includes short-circuit protection and overvoltage protection, both of which help ensure that the device will operate safely and reliably. The device also includes an integrated thermal shutdown feature that will shut down the device in the event that it reaches a temperature that is too high for safe operation.

Summary

The MXHV9910BE is a LED Driver PMIC with integrated high-voltage power switches, designed primarily for commercial lighting applications. With features like temperature sensing, short circuit protection, overvoltage protection, and an ESD protection circuit, it is an ideal choice for projects that require reliable, efficient, and cost-effective performance. Extremely wide operating temperature range also makes it suitable for use in extreme climates. With its unique features, the MXHV9910BE is well-suited to many different projects and applications.
