Working Principle

The BD433M2WFP3-CE2 is a high performance integrated low dropout (LDO) regulator. It has an integrated boost converter and a 3.2MHz 3-phase synchronous rectifier that results in better power efficiency and a smoother output voltage than conventional LDOs. The device has an integrated output current limiter for protection against over-current conditions and an integrated thermal shutdown protection to prevent excessive power dissipation in case of prolonged overload.

The device has an ultra-low minimum operating current of only 30µA and a high efficiency of up to 98%, thereby reducing power consumption and improving system performance. It also features a wide input voltage range of 4.0V to 40V and an output voltage range of 1.2V to 5.5V. The device has low input and output capacitance, which helps reduce noise, ripple and other disturbances.

The BD433M2WFP3-CE2 has a high temperature operating range of -40°C to 125°C and provides excellent performance over a wide range of voltage, current and temperature ranges. It also integrates reverse current protection, which prevents the reverse flow of current when the device is not powered. In addition, the device has a high current capability, making it suitable for applications where large currents are required.
