U6043B-MFP is an integrated semiconductor device designed for use in low power selective and non-selective electromagnetic ballast applications. It integrates a mix of digital and analog functional components all on a single chip. U6043B-MFP is an ideal choice for cost sensitive applications such as inverter circuits, dimmers, and other energy efficient applications.

The U6043B-MFP features an easy to use on-chip self-configurable digital and analog control-interface that enables precise control and flexibility. The device provides a wide range of power management and control options, allowing users to customize their application. The device is available in a range of package sizes, ranging from a 2 cm x 2 cm, to a 2 cm x 3 cm SOP package.

The U6043B-MFP is also applicable in lighting, ballast controllers, commercial, and residential applications. In lighting, ballast control, the device provides power supply pre-charging, dimming and dimming level control. In commercial applications, the device is used to provide power management and line voltage compensation. Additionally, the device features adjustable startup, shutdown, and overtemperature protection.

The working principle of the U6043B-MFP requires a variable pulse-width modulation (PWM) reduction to ensure a controlled effective light level. This variable PWM reduces the steplevel to a manageable value for control purposes. The device supports two control modes, open loop and closed loop. In open loop mode, the device controls the power levels by adjusting the PWM duty cycle and the switching frequency. In closed loop mode, the device maintains a fixed power level and adjusts the PWM duty cycle and switching frequency.

The device also has over-temperature protection built in. The device is able to sense and detect excessive temperatures and is able to automatically shut off to prevent damage. Additionally, the device can be configured with protections and thresholds to prevent over-demand, over-load and brown-out conditions.

The U6043B-MFP is an economical, high performance integrated device, with low power requirements, highly flexible control and power management options, and high reliability. This makes it well suited for use in a wide range of low power applications, including lighting, ballast controls, commercial, and residential applications.
