P9025A-3PAWGI8 is a specialized power management integrated circuit (PMIC) created by Intersil and is capable of fitting in both 4.0mm x 4.0mm packages and 2.5mm x 2.5mm packages. It is typically used in mobile, portable and wearable applications that require power management efficiency, portability, and reliability. This product has a vast application field, ranging from mobile phone and tablet chargers, power tools and gaming consoles, to medical devices, wireless sensors and wearables. It can handle a minimum input voltage of 4.4 Volts and up to 13.2 Volts and can produce a regulated output voltage from 1.7 to 5.5 Volts. It also has an auto-voltage selection feature, which can detect the input voltage and automatically adjust its output accordingly.

The P9025A-3PAWGI8 operates on the principle of integrated circuit (IC) choke. It consists of a large coil of high bandwidth, coupled capacitors and a MOSFET (metal-oxide-semiconductor field-effect transistor). These components work in conjunction to convert the current input of an input voltage into a regulated output voltage, with any excess energy dissipated as heat. It also supports simultaneous operation of both high-efficiency synchronous and low-dropout (LDO) regulators, which enable the device to have improved energy efficiency and high output current capability.

The P9025A-3PAWGI8 is unique in that it offers an energy efficiency of up to 95%, with a maximum quiescent current of just 3.5µA at no load, allowing superior power management capabilities in portable and device applications. It also has an internal compensation network, enabling thermal tracking of the MOSFET to reduce heat dissipation even further. It also supports temperature protection of up to 150°C, under-voltage lockout and current protection for output shorts.

Furthermore, the P9025A-3PAWGI8 features a high-level of noise isolation while allowing small magnetics and external components to reduce the device size, such as in the ultra-small 2.5mm x 2.5mm package option. Its wide input and output voltage range, combined with its industry-leading energy efficiency makes it an ideal solution for the next generation of portable, mobile, and wearable applications.
