LM2852YMXA-1.0 is a high performance DC-DC switching regulator with integrated high-side and low-side switches. It is specifically designed for flyback, forward and SEPIC applications in a very small SIP-8 package. The LM2852YMXA-1.0 operates from a 4.5V to 42V input voltage and provides up to 4A of continuous output current. It is capable of providing up to 4.8A for an output voltage of 5.5V and it is capable of operating with a wide range of output voltages from 1.2V to 24V.

The LM2852YMXA-1.0 provides excellent regulation performance over a wide input voltage range and load conditions. Its high switching frequency of up to 1MHz allows it to deliver very fast transient response and very low output noise. It also utilizes an innovative voltage mode control design that allows it to operate in simple PWM, PFM, and Burst Mode® operation. This allows it to provide excellent efficiency, while operating over a broad input voltage range and load conditions. The LM2852YMXA-1.0 also includes a programmable soft-start feature, which allows for a controlled ramp time of the output voltage when the output is enabled.

The LM2852YMXA-1.0 is designed to work in a number of DC-DC switching converter applications including mobile, industrial and consumer devices. It is ideal for applications such as point-of-load regulation, multi-rail conversion and distributed power systems. The LM2852YMXA-1.0 also features integrated over-current and short-circuit protection, as well as over-temperature protection. This ensures safe operation even in the event of a fault condition.

The working principle of the LM2852YMXA-1.0 is based on a buck-boost topology. In this topology, the input voltage is converted to a regulated output voltage by switching the current between the drain and source of the IGBT high-side switches. The output voltage is regulated by varying the duty cycle of the switching waveform. The high switching frequency allows for a very fast response to changes in load or input voltage and allows for a small external output filter. The LM2852YMXA-1.0 also utilizes a synchronous rectification scheme to improve efficiency while maintaining fast transient response.

In summary, the LM2852YMXA-1.0 is a DC-DC switching regulator with integrated high-side and low-side switches and is suitable for a wide variety of applications including point-of-load regulation, multi-rail conversion, and distributed power systems. It offers excellent performance over a wide range of input voltages and load conditions and has integrated over-current and short-circuit protection, as well as over-temperature protection. Its high switching frequency allows for a very fast transient response and low output noise and its innovative voltage mode control lets it operate in simple PWM, PFM, and Burst Mode® operation.
