Working Principle

The UCD7242RSJT uses the principle of synchronous DC-DC switching regulation to regulate output voltage. It has a high frequency switching topology that switches current between the primary and secondary windings of a transformer. This topology enables the device to provide high performance, high efficiency and high power density.

The UCD7242RSJT has two main operating modes: forced continuous and discontinuous. In forced continuous mode, the device uses a constant on-time and fixed off-time to regulate output voltage. In discontinuous mode, the device uses a variable off-time to adjust the duty cycle of the output voltage in order to maintain a preset output voltage.

The UCD7242RSJT supports remote sensing for output voltage regulation. It uses an external sense resistor to sense the output voltage and adjust the duty cycle of the output voltage in order to maintain the desired output voltage. The UCD7242RSJT also supports voltage positioning and tracking to reduce load-related output voltage changes.

The UCD7242RSJT has an integrated loop compensation circuit that improves the dynamic response of the system by reducing the output voltage’s sensitivity to load current changes. It also provides an adjustable soft-start feature that limits inrush current during power-up.

The UCD7242RSJT also has an integrated over voltage protection circuit for the input and output voltages. This protection circuit prevents the output voltage from exceeding its maximum rating, even in the event of an over voltage condition. The device also provides thermal and short-circuit protection features.
