PMIC or Power Management Integrated Circuits allow efficient control of power within a system while regulating the voltage and saving energy. The LM2852YMXAX-1.2 is a DC-DC Switching Regulator which is used in many applications and embedded systems.

The LM2852YMXAX-1.2 is a low-cost, high-efficiency, tight-regulation power management device that provides four switchable output levels: 1.2V, 1.5V, 1.8V and 2.2V(±10%) from a single input rail. It is made up of a General Purpose Regulator, Switching Regulator and Control Logic, with low noise capabilities and a wide input range from 4.5V to 16V. This device simplifies the implementation of automatically and accurately regulated multiple output power management systems in digital consumer applications.

The device incorporates an Enhanced Constant Frequency (ECF) topology and a lifetime limited drive circuit. It uses a unique approach in power management by combining the advantages of both switching and linear regulators with the simplicity of a single IC solution. With the same total power output, the LM2852YMXAX-1.2’s switching regulator can achieve much higher efficiency than the linear regulators.

The application field of LM2852YMXAX-1.2 can cover various USB- and AC-powered products, such as DVD players, CD players, TV set top boxes, Blu-ray players, portable media players, audio amplifiers and DSPs, LCD/LED TVs and monitors, as well as many other power management applications. It is an ideal power supply for controlling a high current DAC or op-amp.

The working principle of LM2852YMXAX-1.2 is based on the requirement of the load current and offers the output voltage by switching between 1.2V, 1.5V, 1.8V and 2.2V with fast rise and fall times. At the switching frequency of 250kHz, the current limit is activated to protect any via inductances and high voltage spikes. The device provides thermal protection during overloads and overtemperature events.

The LM2852YMXAX-1.2 is an efficient and cost-effective solution for DC-DC switching regulator control and it is available in a TDFN-14 package. It also offers advanced features such as short-circuit protection, over-current protection and thermal protection. The device is RoHS-compliant and has an operating temperature range from -40°C to +85°C.

Overall, the power management solution from LM2852YMXAX-1.2 provides users with flexibility and reliability, reducing time-to-market and costs. It is suitable for automotive, commercial and industrial applications, as well as many other power management applications.
