The TPS658622AZQZR is a Multi-Output, High Efficiency, High-Integration Controller with Sequencing, designed by Texas Instruments, targeted for applications such as Smartphones, Tablets, and Notebooks. The device provides up to 5.85A of output current across five integrated buck regulators and one LDO, along with four additional LDOs connected externally.

The TPS658622AZQZR is a low power, high efficiency, advanced power management integrated circuit that enables mobile device manufacturers to reduce power consumption, package size, and component count. It can provide up to 5A of output current from the five voltage regulators, either independently or in fixed sequence. For applications such as powering Bluetooth, ZigBee, ultra-low power cellular basebands and other functions with low power consumptions, the TPS658622AZQZR can also support up to four additional LDOs externally.

The TPS658622AZQZR is designed to be used in smartphones, tablets, and notebooks and in other battery-powered systems. Each of the voltage regulators can be individually programmed to the desired output voltage. This ensures that each system component is powered with the optimal voltage, maximizing the efficiency of the system.

The TPS658622AZQZR utilizes pulse-width modulation (PWM) sequencing to upsequencing the regulators. This provides a better control of output current, reduces loss of power, and also reduces the inrush current. The device includes a programmable 800kHz constant-on-time (COT) topology to enable fast transient response and provide high efficiency over the entire load range of each regulator.

The TPS658622AZQZR also includes a number of integrated protections to protect the device from faults such as over-voltage, under-voltage, over-current, and over-temperature. The device also includes built-in diagnostics, such as cycle-by-cycle current limit and thermal shutdown, designed to prevent damage or output failure. In addition, it also provides three reset output signals that can be used to reset other system components.

In conclusion, the TPS658622AZQZR is a high-efficiency, high-integration controller with sequencing and protection that is designed to reduce power consumption, component count and package size in smartphones, tablets and notebooks. It is an ideal device for applications requiring high current output with multiple voltage regulators and external LDOs. The device utilizes pulse-width modulation (PWM) sequencing and a programmable 800kHz COT to enable fast transient response and provide high efficiency. The TPS658622AZQZR is a reliable, feature-rich platform for powering mobile applications.
