P9221-0AHGI

The P9221-0AHGI is a power management integrated circuit (PMIC) developed by Renesas Electronics, designed specifically for high performance devices with tight regulation of output voltage. This specialized PMIC enables engineers to focus on the core functionality of their system design without worrying about combinations of discrete devices necessary to deliver reliable power to other subsystems.

The P9221-0AHGI is ideal for a wide range of applications, most notably battery operated and portable equipment such as smartphones, tablets, cameras, and other consumer electronics. The device has been designed to meet the needs of these applications in terms of power density, extensive voltage and current output range, top notch transient protection, low power consumption and extremely low quiescent current.

The main feature of the P9221-0AHGI is its four buck converters with integrated power switches, two boost converters, and two linear regulators that are all capable of providing very precise output voltage control. All of these components are integrated into a single 15x15mm QFN package, making it one of the smallest package solutions for power management available today.

The most impressive performance metric of the P9221-0AHGI is its excellent power efficiency, allowing it to achieve up to 96% efficiency across all loads. This is achieved by employing a number of advanced power conversion techniques, including adaptive on-time control, adaptive voltage positioning, as well as skip and burst modes. These power saving modes allow the device to optimize its power output according to the load demand and actively reduce power consumption when operating at low load currents.

In addition to excellent power efficiency, the P9221-0AHGI offers a number of features designed to optimize system performance. It supports an input voltage range from 2.5V to 5.5V and can deliver output current up to 6A for the buck converters and up to 600mA for the two boost converters. The P9221-0AHGI also includes overvoltage, undervoltage, and short circuit protection as well as inductor temperature protection.

The P9221-0AHGI is an incredibly versatile PMIC that can cover a wide range of applications, making it an ideal choice for system designers looking to maximize power efficiency and reliability. With its integrated power switches and advanced power conversion techniques, the P9221-0AHGI is a great choice for applications like smartphones, tablets, and other consumer electronics.
