MC34727BFCR2 is a DC-to-DC switching regulator from the MC34727BFCR2 product family of voltage regulators. This voltage regulator can be used to provide a regulated voltage source for a variety of applications. It is designed to replace linear regulators, providing improved energy efficiency and reduced waste heat.The MC34727BFCR2 is a buck voltage regulator, and is characterized by a step-down conversion between the input and output voltages. This type of regulator provides a cost-effective solution to deliver a prescribed output voltage from a higher input voltage. The primary applications for the MC34727BFCR2 are the low output voltage applications such as LED drivers, smart phone chargers, netbooks and other power-sensitive electronic devices.The MC34727BFCR2 is a two-phase synchronous buck regulator integrated with a low-side MOSFET and a high-side MOSFET. This buck regulator works by switching the high-side MOSFET on and off in synchrony with the transformer’s primary-side switching, such that their inductive energy is fully discharged into the load. The output of the regulator is controlled by modulating the duty cycle of the high-side MOSFET. Since the load current is shared between the high-side and low-side MOSFETs, the current ripple is reduced significantly, compared to other single-switch buck regulators.The MC34727BFCR2 also offers a high level of integration and protection features. It contains several features and control modes that can be used to achieve a wide range of system requirements such as current limit protection, thermal protection, overvoltage protection, and undervoltage lockout. The regulator also offers an adjustable output voltage and soft start to reduce the inrush current during power-up. Additionally, this regulator has an efficient, low noise, and reliable operation over a wide range of temperatures and frequencies.Apart from protection and operation features, the MC34727BFCR2 also has a high efficiency and small form factor. This buck regulator is ideal for applications that demand reduced size, noise, and a low overhead cost. The regulator operates at a switching frequency of up to 3.5MHz, eliminating the need for an additional power supply with a higher output current. Also, the MC34727BFCR2 has a low-noise operation, which eliminates the need for additional filtering components in the system.Overall, the MC34727BFCR2 is designed for applications requiring regulated, low voltage DC-to-DC conversion. This buck regulator offers high efficiency, small form factor, low noise, and protection features. It also provides adjustable output voltage, overvoltage and undervoltage protection, and current limit protection. The MC34727BFCR2 is suitable for low output voltage applications such as LED drivers, smart phone chargers, netbooks and other power-sensitive electronic devices.
