3 Description

The TPS65219 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 3.5A and 2x

2 A. The converters require a small 470nH inductor,

4.7μF input capacitance, and a minimum 10μF output

capacitance per rail depending on the switching mode

configuration.

Two of the LDOs support output currents of 400mA at

an output voltage range of 0.6V to 3.4V. These LDOs

support bypass mode, acting as a load-switch, and

allow voltage-changes during operation. The other

two LDOs support output currents of 300mA at an

output voltage range of 1.2V to 3.3V. 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.
