PMICs, or Power Management ICs, are a type of integrated circuit (IC) that regulates power in electrical systems. They’re widely used in smartphones, computers, and other electronic devices to ensure efficient power distribution and minimize energy waste. Voltage regulators, one type of PMIC, ensure that the voltage of a device’s power supply remains constant despite changes in the electric current. DC DC switching regulators are one type of voltage regulator. XC9261B33CER-G is a DC DC switching regulator.

Application Field

The XC9261B33CER-G is designed for use in low-voltage, high-current applications. It features adjustable output voltage, fast dynamic responses, and low power consumption. It is commonly used for power supply in industrial, automotive, healthcare, and home appliances. It is also used in mobile phones, digital still cameras, camcorders, LCD TVs, printers, and other portable electronic devices. With its high power efficiency and low electromagnetic interference, it is ideal for applications that require large amounts of electricity.

Working Principle

A DC-DC converter is an electronic circuit used to convert a voltage from one level to another. The XC9261B33CER-G DC-DC converter consists of an input stage, a feedback control system, and an output stage. The input stage normally consists of a rectifier, voltage divider, and filter capacitor. The feedback control system is used to regulate the output voltage. It takes information from the output voltage, compares it to a reference voltage, and adjusts the input voltage accordingly. The output stage consists of an oscillator, a switch, and an inductor. When the switch is turned on, the oscillator turns it off again, so that the inductor can store energy. The stored energy is then released through the output stage, providing a regulated DC voltage.

The XC9261B33CER-G DC-DC converter utilizes two power switches and two synchronous rectification MOSFETs. It has a maximum continuous current of 3 A and can deliver up to a maximum of 6 A of output power. The input voltage range is from 4.5 V to 37 V and the output voltage is adjustable from 0.8 V to 8 V. It features over-current protection, thermal shutdown protection, under-voltage lockout, over-voltage protection, and over-temperature protection.

In conclusion, the XC9261B33CER-G DC DC switching regulator is a useful PMIC for applications that require high power efficiency and low electromagnetic interference. It has adjustable output voltage, fast dynamic responses, and low power consumption. With its various protections and adjustable output voltage, it is well suited for a variety of applications.
