The MCZ33887EKR2 is a popularly used power electronic device made by ON Semiconductor. It falls into the category of PMIC-Motor Drivers, Controllers and it plays a key role in controlling the motor’s voltage and current under specified conditions. The MCZ33887EKR2 is comprised of a two-phase, low-voltage, low-side, DC-to-DC synchronous buck controller, six integrated N-channel MOSFETs, and protection features.

The main purpose and application field of the MCZ33887EKR2 is to aid in providing and controlling manageable power within the specified environment. It provides accurate control of the absolute and differential voltage between its input and output, while maintaining perfect synchronism between each phase of the buck converter. This type of precision makes the MCZ33887EKR2 perfect for applications such as cooling solutions, energy efficiency solutions and managing node-voltage regulation for high-speed processors.

The working principle of the MCZ33887EKR2 is based on the principle of a DC-to-DC synchronous buck converter. The converter is comprised of two-phases, two high-side drivers, two low-side drivers and a non-paralleled external MOSFETs. The two components together form an H-bridge structure. The two high-side drivers and two low-side drives each switch on their respective sides of the H-bridge and the external MOSFETs act as an additional synchronous element to bring the two-phase to its ideal efficiency and keep it regulated.

The switching behavior of the H-bridge is controlled by the MCZ33887EKR2’s integrated architecture which includes an internal control loop and an input clock. The control loop ensures that the output voltage remains within the specified limits while the input clock runs at the same frequency of the H-bridge. The duration of the pulse signals delivered by the MCZ33887EKR2 can be easily adjusted according to the requirements. Furthermore, the input side current limit and the output side current limit offer additional safety and protection.

The MCZ33887EKR2 can also respond to changing conditions like input and load variations quickly, thereby providing continuous regulated voltages and currents over a wide range of inputs and loads. This feature ensures that the MCZ33887EKR2 has greater stability than other controllers and provides superior performance and less distortion of output voltages.

The MCZ33887EKR2 is also equipped with protection features such as over-voltage protection, under-voltage protection, thermal protection, and open-phase protection which make it safe to be used in adverse environments. It is also capable of handling large amounts of power with little to no heat dissipation. The MCZ33887EKR2 also has a wide temperature range and can operate in temperatures up to 155°C.

These features make the MCZ33887EKR2 a highly popular power electronic device and it is widely used in numerous applications in the industrial, automotive and consumer electronics sectors. It provides extensive and reliable protection over varying input and load conditions and ensures outstanding performance in the long term.
