PMIC (Power Management IC) plays an important role in the production of power conversion and manage in modern electronics. Voltage Regulators is one of the categories under PMIC, it can provide a constant voltage, keeping a constant output power supply and maintain the adequate current for the device in case a larger load is forced on the power supply.DC DC Switching Regulators, in particular, is widely used in telecommunication, automotive, electric vehicle and system large current, small current and other fields.

LTC3118MPFE#PBF is a step-down DC/DC switching regulator particularly designed for electric vehicles and battery applications. It can adjust the output voltage from 1.2V to 24V with a maximum output current of 3 A. It can be applied to electric vehicles, mobile computing and military markets.

Apart from onboard input voltage range (2.2V-32V), the input filter can be optimized and improved thanks to its wide input range acceptance. It integrated support components allows us to design a smaller footprint with high efficiency, allowing us to easily fit in a tiny size package like the SOIC and MSOP package.

Now, let’s have a closer look to the working principle of LTC3118MPFE#PBF. It uses a mixed-mode architecture that combines a linear regulator and a synchronous buck regulator in one integrated package. Generally, the switching regulator is a high-efficiency converter that includes both “buck” and “boost” converter abilities. This can be achieved through the control circuit in the converter that manage the switched power output and the voltage regulation process. The buck converter decreases the input voltage, while the boost converter increases the input voltage.

The LTC3118MPFE#PBF works in two operation modes: Burst Mode and Pulse Skipping Mode. During the Burst Mode operation mode, the device is operating at its highest efficiency with a pulse width modulated (PWM) current limit that limits output current during its high current input/output operation. During the Pulse Skipping Mode, the PWM signals are gated to reduce the total number of switching cycles and improve the efficiency at light loads.

The LTC3118MPFE#PBF can be used in a number applications, like Point of Load (POL) regulation, distributed power architecture, microprocessor and FPGA core supplies, automotive systems and SIM card readers. When used in electric vehicles and battery applications, it can help to increase the power efficiency and reduce its heat dissipation. Finally, it capabilities to operate with the Rail-to-Rail N-Channel MOSFET converter allows the regulation of loads higher than the output voltage. It can solve the issue of power dissipations that usually occurs with traditional boost converter configurations.

In conclusion, LTC3118MPFE#PBF is a reliable power management IC device which is popularly used for its wide range of applications. With its unique Burst Mode and Pulse Skipping Mode operations, its ability to have Rail-to-Rail N-Channel MOSFET converter and its special integrated support components, the device offers efficiency of operation, high compatibility, stable output voltage and low heat dissipation, allowing designers to create truly small and efficient power supplies. Its attractive features makes it a desirable DC/DC switching regulator for electric vehicles and battery applications.
