It is ideal for use in power supplies, DC/DC converters, and DC/AC inverters. In addition, it is suitable for use in embedded systems, robotics, and digital control applications.

product is designed to meet the requirements of a wide variety of applications and its features, such as programmable switching frequency, input and output voltage range, power-saving features, and low component count, make it suitable for a broad range of DC/DC and AC/DC (off-line) SMPS applications.

The working principle of MC34063LBKEVB is based on the well-known buck-boost topology. Buck-boost topologies are widely used for DC/DC conversion, especially when a voltage conversion between two different voltage levels is required. The core of this switching regulator is a digital control circuit, which actuates the internal power switches to regulate the output voltage. The digital control circuit monitors the output voltage via a sense pin and provides feedback into the feedback loop, which then regulates the output voltage.

The MC34063LBKEVB features an adjustable soft-start circuit that limits inrush current during the power-up transition. It also has a current limit, a short circuit protection, adjustable switching frequency and over temperature protection. The switching frequency can be adjusted to optimize both efficiency and noise level. The over-temperature protection ensures that the output voltage is maintained at the desired level, even under extreme temperature conditions.

In conclusion, the MC34063LBKEVB is a versatile and efficient device for use in a wide variety of applications, such as AC/DC power supplies, DC/DC converters, LED lighting, automotive power converters and motor control systems. The device is easy to use and is well suited for low-/medium-power DC/DC and AC/DC (off-line) SMPS applications.
