The R85049 / 86-24Z02 is a single converter part of the family of semiconductor devices which are specifically designed to convert a wide range of input voltages into standard output voltages. Its application field lies mainly in low-voltage, high-current applications which require fast and reliable conversion from one power source to another. In comparison to linear regulators, switching regulators offer improved load regulation, higher power efficiency and better step load accuracy.

The R85049 / 86-24Z02 is a DC-DC switching regulator with an input operating voltage range of 12V to 55V. It can provide output current up to 3A with output voltage options of 24V, 12V and 5V. It features low ripple noise (<10mV) and it also has the ability to synchronize with an external clock up to 24MHz. The device also features an integrated power-good signal which indicates the output voltage status and short-circuit protection, offering a robust design.

The working principle of the R85049 / 86-24Z02 is based on a simple and efficient buck-boost regulator topology. This topology works on the principle that the output voltage is regulated by a control circuit, consisting of an error amplifier, a reference voltage, and a PWM comparator. The PWM comparator converts the output voltage information into a high-frequency pulse-width modulation signal, which is used to control a power MOSFET. The power MOSFET then acts as a switching element, switching the input voltage to the output voltage as per the specifications.

The buck-boost regulator uses two main components, namely, a buck converter and a boost converter, with the two connected in series. The buck converter is connected to the input source, while the boost converter is connected to the output load. In this arrangement, the buck converter reduces the input voltage to the output voltage, while the boost converter increases the output voltage further to deliver the desired output voltage. This topology offers enhanced reliability and increased power efficiency.

In summary, the R85049 / 86-24Z02 is a DC-DC switching regulator that offers a wide range of input voltages and output voltages. It is specifically designed for low-voltage, high-current applications which require fast and reliable conversion from one power source to another. The device works on a buck-boost regulator topology, which uses two main components in series, namely, a buck converter and a boost converter. The device also features low ripple noise and power-good signal, making it a robust design option.
