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.
