PMIC - Power Management - Specialized

Power Management ICs (PMICs) are semiconductor solutions specifically designed to manage the power portion of a wide variety of consumer, industrial, and communications applications. PMICs simplify the design of circuits by offering a single integrated solution that does not need to be connected to external components. PMICs are manufactured with different types of capabilities, such as voltage regulation, thermal protection, and control features. The specific features available depend on the type of PMIC and the manufacturer.

One type of PMIC is the P9235-11NDGI8. This device is a High-efficiency Synchronous Buck Regulator 5A synchronous buck regulator which combines high efficiency and small footprint with a hardware Power-On Reset and current sensing capabilities.

The P9235-11NDGI8 is designed to be used in a variety of applications, such as power management, battery charging, and LED lighting. It is a versatile and highly efficient regulator that is suitable for low voltage applications. The device operates between 2.5V and 5.5V, with a minimum output current of 500mA and maximum output current of 5A.

The P9235-11NDGI8 has a feature set that includes a programmable switching frequency of 200kHz to 2MHz, accurate input current sensing, adjustable advanced Current Limit foldback, adjustable Power-On-Reset, and adjustable Soft-Start. The device also has a latch-off mode of operation that turns off the power under overload or over temperature conditions.

The P9235-11NDGI8 operates using a buck topology. This topology involves switching of the input voltage at a fixed frequency. With this approach, the output voltage is always equal to the input voltage divided by a fraction, such as two-thirds, which is used to regulate the output voltage. This approach is efficient because it allows for better energy conversion compared to other controllable power supplies.

The P9235-11NDGI8 allows for the adjustment of the frequency which is used to switch the input voltage. This frequency allows for improved efficiency and greater control over output voltage stability. The switching frequency can be adjusted from 200kHz to 2MHz using external resistors. This makes it possible to make adjustments to the output voltage in order to maintain a desired voltage level.

The P9235-11NDGI8 is designed to maintain an accurate output voltage through its current sensing and Power On Reset capabilities. It is capable of operating under low input voltage conditions and offers low quiescent current with no load. The device also supports adjustable current limit foldback which helps protect the device from overload. The device also has a latch-off mode of operation, which turns off the power under overload or over temperature conditions.

The P9235-11NDGI8 is an efficient and versatile power conservation solution that can be used in a variety of applications. With its adjustable switching frequency, adjustable current limit foldback, and latch-off mode of operation, the P9235-11NDGI8 offers a high level of protection and regulation for a wide range of applications.
