3 Description

The TPS6522005-EP is a Power Management IC

(PMIC) designed to supply a wide range of SoCs in

both portable and stationary applications. The device

is characterized across an ambient temperature

range of -55°C to +125°C, making the PMIC an

excellent choice for various industrial applications.

The device includes three synchronous stepdown DCDC

converters and four linear regulators.

The DC-DC converters are capable of 1x 3.5 A and

2x 2 A. The converters require a small 470 nH

inductor, 4.7 μF input capacitance, and a minimum

10 μF output capacitance per rail depending on the

switching mode configuration.

Two of the LDOs support output currents of 400

mA at an output voltage range of 0.6 V to 3.4 V.

These LDOs support bypass mode, acting as a loadswitch,

and allow voltage-changes during operation.

The other two LDOs support output currents of 300

mA at an output voltage range of 1.2 V to 3.3 V.

These LDOs also support load-switch mode.

The I2C-interface, IOs, GPIOs and multi-function-pins

(MFP) allow a seamless interface to a wide range of

SoCs.
