MCZ33812EK

MCZ33812EK is an integrated highly efficient step-down converter andLDO regulators which can deliver a continuous current of 3A and 3.2Arespectively. It is a power management integrated circuit (PMIC) which offers versatileperformance, efficiency and accuracy to address wide load rangedemanding applications such as wireless chargers, smartphone/tabletmainboards, small electric power converters and so on.

Application

The MCZ33812EK offers many advantages for its target applications: inaccuracy, high efficiency, flexible output voltage, built-in over current, over temperature protection and OVP. The converter provides the flexibility required in terms of input voltage, output voltage and operating current range, to suit any application, this incorporates features like over current protection, over voltage protection, thermal shutdown and output current monitoring. The conversion process starts with the input voltage, which is then converted to a low command voltage that is fed to the Buck regulator. The output of the converter is then regulated to an adjustable level based on the command voltage.

For application situations that require different voltage outputs, the MCZ33812EK includes a programmable output voltage range. This range can vary based on the user’s needs, ranging from 0.90V to 3.60V. Providing adjustable output voltage makes the MCZ33812EK ideal for industrial and consumer applications.

Also, the MCZ33812EK features built-in current limiting for both the high-side and low-side of the device. This provides protection for components in the event of an overload condition. The device also contains thermal protection and OVP. The thermal protection will ramp down the output current if the chip gets too hot, and the OVP will adjust the current to protect the system from an overvoltage condition.

Working Principle

The MCZ33812EK works by using an advanced modulation scheme called pulse-width modulation to control the current flow. The modulation scheme works by changing the period of the pulse-width or on-time of the output signal’s waveform. If a higher voltage is needed, then the on-time is increased, and if a lower voltage is needed, then the on-time is decreased.

The MCZ33812EK also uses a switch-mode design that improves conversion efficiency, enabling the device to run at higher load currents. The switch-mode design effectively reduces switching frequency and switching losses, which increases efficiency. The reduction in switching losses also creates less heat, making the module more effective in the long run.

The MCZ33812EK also offers an adjustable output voltage through a digital interface. This allows the user to adjust the output voltage via software, giving the user more control over their applications. The adjustable output voltage can be set from 0.90V to 3.60V.
