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 it suitable for various
industrial applications. The device includes three
synchronous stepdown DC-DC converters and four
linear regulators.
The DC-DC converters are capable of 1x 3.5 A and
2x 2 A. They require a small 470 nH inductor, 4.7 μF
input capacitance, and - depending on configuration -
minimum 30 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. They
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.
