3 Description

The TPS6521905 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 -40°C to +105°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.

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. The

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.
