3 Description
The TPS65219-Q1 is a Power Management IC
(PMIC) designed to supply a wide range of SoCs in
automotive applications. The device is characterized
across an ambient temperature range of -40°C to
+125°C, making the PMIC an excellent choice for
automotive applications. The device includes three
synchronous stepdown DC-DC 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.
