The device has a boosted output, with a selection of power sources including up to four LDOs, which can be used to regulate down voltages up to 6.25 V. The device is also capable of operating at power levels up to 10 W, making it ideal for use in portable applications such as tablets, portable media players and cellular phones.

Application field:

The TPS65552ARGTR is especially suitable for use in battery-powered applications. It offers high efficiency, low ripple and noise characteristics, and high precision control of the output voltage. Additionally, the device can be used to power ICs, such as microprocessors, GPU cores, flash memory and other components, including two or more USB ports. This makes it ideal for use in power management systems for digital appliances and other devices.

Working Principle:

The TPS65552ARGTR device is designed to provide regulated power for digital communication devices. The device uses a digital control architecture to regulate the output voltage. Input power is supplied to the device via two MOSFETs, which act as switches that pass the current to the output. An integrated linear regulator (LDO) then regulates the voltage before the current is passed to the output. The control circuit of the device is comprised of a pulse-width modulation (PWM) generator, an internal clock and a dedicated linear controller. The internal clock allows the device to operate at an optimal clock frequency and the dedicated linear controller ensures that the output voltage is always at the desired setpoint.

The TPS65552ARGTR has a dedicated linear controller, which makes it very efficient in terms of power dissipation. The device is also designed for low ground bounce and fast transient response. Additionally, the device has protection features that help reduce the effects of output overvoltage, load current overloads, undervoltage conditions and short circuits. The device also offers soft start and a power-save mode which can be enabled when the load current is low.

In summary, the TPS65552ARGTR is a high-efficiency, multi-output power management integrated circuit (PMIC) with digital control capabilities that makes it ideal for use in smartphones and other digital communication devices. The device offers a wide range of power sources, protection features and flexible control, making it perfect for applications such as portable media players, cellular phones, and battery-powered applications. Its high efficiency and low ripple and noise characteristics make it an excellent choice when it comes to providing regulated power.
