PMIC - Voltage Regulators - Linear

The S-1167B29-I6T2G is a Linear Voltage Regulator PMIC (Power Management Integrated Circuit). This PMIC\'s linear voltage regulation works by positively regulating an input voltage, obtaining an output voltage that is greater than the input voltage, with the possibility of increased output current. In today’s technological world, these types of Voltage Regulators have become more popular due to their linear outputs for low-noise operation, as well as their low cost, simple design, and efficient performance.

Application Fields

The S-1167B29-I6T2G Voltage Regulator PMIC is primarily used for audio and video equipment, car CD player systems, digital cameras, communication devices, PC motherboards and add-on cards, audio/video power amplifiers, and any other electronic device that needs the regulation of electrical signals. This type of PMIC is also suitable for automotive applications, as it features built-in protection circuits such as fold-back current limiting, over-current protection, and temperature protection.

Working Principle

The S-1167B29-I6T2G is designed to provide a reliable and stable output voltage. It has an input voltage range of 4.7 to 28 volts and an adjustable output voltage range of 1.2 to 27 volts. It features a current output of up to 6A and an output overload of 150mV. The voltage regulation is achieved by using a positive feedback loop, which compares the output voltage to a reference voltage and adjusts the control element accordingly. The output voltage is determined by the output of the reference voltage and the output of the control element. If the output voltage is greater than the reference voltage, then the control element will be adjusted to reduce the output voltage. If the output voltage is lower than the reference voltage, then the control element will be adjusted to increase the output voltage.

The S-1167B29-I6T2G also features thermal protection, which helps protect the device from overheating. It has an operating temperature range of -40 to 85°C. Additional protection includes reverse polarity and over-voltage protection, as well as under-voltage protection.

The S-1167B29-I6T2G is a reliable and cost-effective PMIC for voltage regulation applications. It has a wide input voltage range, adjustable output voltage range, current output up to 6A, and thermal protection. This PMIC can be used in a wide range of applications such as audio/video equipment, car CD player systems, digital cameras, communication devices, PC motherboards and add-on cards, and audio/video power amplifiers.
