Modern electronic systems demand more variability, performance and efficiency while consuming less energy and staying compact. Voltage regulators are essential components of these systems. PMIC (power management integrated circuits) enable efficient, DC-DC conversion and low noise power delivery with a broad range of output voltages and protection features, even in the harshest of environments.

The XC9235A18DMR-G is a voltage regulator IC in the DC-DC switching regulator family. It is a PMIC,monolithic integrated circuit built with a voltage regulator, switches and inductors that enables superior power delivery to modern portable devices such as PDAs, smartphones, tablets, cameras and high-end digital consumer electronics. Its small size and flexibility make it suitable for power delivery in multi-rail systems.

The XC9235A18DMR-G has multiple pins, including an all-purpose pin, an enable pin, a reset, a power-on reset, and a voltage feedback pin (VFB). It has a maximum operating junction temperature of 125C, and a maximum output current of 20mA. The device has a high current capacity up to 1.3A, integrated temperature protection and support for over voltage protection. It is a high efficiency, low noise, DC-DC regulator with high output voltage accuracy, provides robust protection against fault conditions and supports both operation modes, pulse frequency control and peak current limiting PFC.

The XC9235A18DMR-G is ideal for use in mobile devices where high efficiency, low noise and board area are key requirements. It is also suitable for industrial and consumer applications such as LED drivers, LCD displays, embedded systems and other automotive, communications and audio/visual applications where current and temperature regulations are necessary.

The working principle of the XC9235A18DMR-G is based on the buck and boost switching regulator topologies. This voltage regulator is capable of regulating a power supply output voltage over a wide range by producing an on-demand direct current (DC) output. At the heart of the XC9235A18DMR-G is a high-frequency (100KHz) switching regulator, consisting of two main components, an inductor and a switch (FET).

The switching principles of the XC9235A18DMR-G are simple. The FET switch is turned on and off in a predefined pattern, at a switching frequency that is determined by the user through the on-chip control circuitry. When the switching control logic turns on the FET, the inductor charges with energy, storing it in its magnetic field. The stored energy is eventually used for the conversion of the DC input voltage and is used to drive the load.

The XC9235A18DMR-G also includes several features that further increase its efficiency. These features include over-current protection, over-temperature protection, pulse frequency modulation for lower power ripple, Synchronous Rectification for higher efficiency and soft-start to gradually ramp the output voltage.

Unlike other types of voltage regulators, the XC9235A18DMR-G provides excellent power delivery and higher efficiency while consuming less power than other solutions in the same class. It is ideal for providing power to mobile devices and other electronic systems that require high efficiency without compromising on performance.
