PMIC (Power Management ICs) form the basic building blocks of almost any power management system. They direct, control and manage the power flow between the power source and the load, and also monitor, adjust and manage the voltage and current levels. The MC33063AVDR2 is a high performance DC DC switching regulator from ON Semiconductor, and is part of their extensive family of voltage regulators.

The MC33063AVDR2 is a monolithic integrated circuit (IC) which switches current mode in the range of 2.5 to 50V. It is a pulse width modulation (PWM) control device which regulates the output voltage between 0.8 and 5.2V with ±2% accuracy. It provides fast transient responses with just 50 mV overshoot and low dropout voltage over a wide temperature range. The device can also operate in an open loop or in a closed loop mode, making it a highly flexible and programmable switching regulator.

The MC33063AVDR2 provides a range of features and advantages compared to traditional linear voltage regulators. The device is designed to dissipate very low heat, which reduces the need for external heatsinks, saving size and cost. Additionally, the device is highly efficient, up to 95% depending on load. This leads to a significantly lower operating temperature, reduced complexity, and improved system reliability.

The MC33063AVDR2 offers several operating modes and a wide range of protection features. It includes a current limit protection which protects against the over-current conditions, a frequency foldback protection which reduces the switching frequency under heavy load, and a thermal shutdown protection to protect against excessive heat. It also features a low start-up current and a diode-less connection, making it more efficient and reliable.

The primary application field of MC33063AVDR2 is in automotive, industrial, consumer and communication markets. It is an ideal choice for managing the power supply of lighting, motors, LEDs, audio systems, power conditioning units and power converters. It is also suitable for applications such as battery management systems, wireless charging, lithium ion battery charging, voltage and current monitoring, testing, instrumentation and telecommunications.
