ADP5034ACPZ-R2 Application Field and Working Principle

ADP5034ACPZ-R2 is a processor multifunction power management IC (PMIC) designed for smartphone, PDA, and other mobile devices applications. This high performance power management IC is housed in a tiny TDFN-2x2-10L 3mm x 3mm package and delivers unprecedented power efficiency for up to 4 channels of output.The ADP5034ACPZ-R2 has a range of features that provide highly efficient power conversion and management capabilities for battery powered applications. It has four configurable linear regulators, four configurable switching regulators, an adjustable channel system-away channel for dynamic channel switching, and programmable logic control for managing system functions. The ADP5034ACPZ-R2 is compatible with both I2C and SPI interfaces, allowing it to be integrated into existing systems and easily controlled by external microcontroller.The ADP5034ACPZ-R2 supports a wide input voltage range of 2.6V to 5.5V, which makes it suitable for use in low power applications. The IC also features a low quiescent current of 10uA, and a low dropout voltage of 0.3 V. This ensures that the ADP5034ACPZ-R2 can operate its channels without wasting energy. It also features a low output voltage ripple of 0.5%.The ADP5034ACPZ-R2 linear regulators can be configured for up to four channels of output, each with a voltage range of 0.9V to 5V. These regulators can function as voltage followers or adjustable regulators, allowing them to provide an output voltage that is regulated according to the load current.The ADP5034ACPZ-R2’s switching regulators can be configured for up to four channels of output, each with voltage range of 0.9V to 5V and peak current capability of up to 18A. These regulators are implemented using a pulse width modulation (PWM) technique, which enables high power conversion efficiency. Switching regulators are ideal for applications that require high power output, since they can provide more power without incurring a large power loss.The ADP5034ACPZ-R2 also features an adjustable channel system-away channel that can be used to minimize power consumption when the system is idle. The system-away channel can be configured to be triggered by an external signal, such as a system-wake-up signal, or to be triggered after a set time delay, allowing the system to save energy in between activities.In summary, the ADP5034ACPZ-R2 is a highly integrated and efficient processor PMIC for mobile devices applications. It supports up to four channels of output, both linear and switching regulators, and its adjustable channel system-away channel enables the system to conserve energy when idling. This makes the ADP5034ACPZ-R2 a great choice for power conversion and management in battery powered systems.
