PMIC - Battery Chargers
The RT9451GQW is a low voltage system chipset designed for applications such as PDAs, smart phones, and various other portable consumer electronics devices. It features an on-chip step-down DC-DC converter, power FETs, and several other power management functions. It is designed for use in applications powered by an alkaline battery or two-cell lithium-ion battery. The RT9451GQW is designed to be energy efficient, providing clean power even when the input voltage drops to low levels.
Application Field
The RT9451GQW is well-suited for use in applications powered by an alkaline battery or two-cell lithium-ion battery. It is designed to be low power, high efficiency and offer high reliability. This makes the RT9451GQW suitable for battery powered applications such as PDAs, smart phones, portable media players, and other consumer electronics devices. It is also suitable for other low voltage applications where efficient operation with clean power is desired.
Working Principle
The RT9451GQW is a step-down DC-DC converter, powered by an alkaline battery or two-cell lithium-ion battery. It features power FETs and other power management functions. The output voltage is adjustable, ranging from 3.2V to 5.4V. It can deliver up to 1.5A of load current when the input voltage is between 2.8V and 5.5V.
The RT9451GQW can maintain high efficiency even when the input voltage is low. It integrates several functions that ensure highly efficient operation, such as cycle skipping, multi-phase synchronous rectifying, and wide output voltage tracking. These features allow the RT9451GQW to deliver clean power at high efficiency. It also features over-temperature protection and over-current protection to ensure safe operation.
The RT9451GQW also features a built-in power management system that can be configured to operate in low power or ultra-low power mode, depending on the application. This allows the RT9451GQW to provide maximum efficiency for battery powered applications, prolonging the life of the battery.
