STLUX385

The STLUX385 is an advanced power management device from STMicroelectronics. It is designed to improve power delivery in small form factor applications, including displays, wearables, and other IoT products. This power management integrated circuit (PMIC) provides high efficiency, flexibility, and scalability for a range of device requirements.

The application field of the STLUX385 includes a range of electronic systems such as display control, automotive instrumentation, portable medical equipment, projectors, POS systems, wearables, etc. The PMIC is equipped with dual channel, step down converters and two channel boost converters that can support 1.8V to 12V input ranges and output voltages up to 28V. This high accuracy PMIC also features a range of features that make it suitable for high performance applications.

The working principle of the STLUX385 involves several different components. The first step is the input stage, where the power is supplied to the system. The PMIC then sends the input power to an adjustable dual channel Step-Down converter, which optimizes the power source for the output. The Step-Down converter is designed to maintain a constant output voltage throughout its duty cycle, with low ripple over a wide input voltage range. It also consumes very little power and is built with advanced power technologies for efficient operation.

Next, the adjustable dual-channel Boost converter controls the output voltage, providing a higher output voltage with its improved power efficiency. The PMIC is also equipped with a low-dropout (LDO) regulator, providing high performance and flexible power solutions. It is also provided with a number of protection features, such as short circuit, current limit, over voltage, and temperature control. Finally, there is the power monitoring system, which ensures the stability and safety of the system.

The STLUX385 is an ideal solution for reliable and efficient power management in small form factor applications. It offers high efficiency and reliability, as well as integrated features like monitoring, protection, and scalability. This advanced power management device makes it easier for manufacturers to create small form factor products with reliable and efficient power delivery.
