3 Description

The TPS65215-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 two

linear regulators.

The DC-DC converters are capable of 1x 3.5A and 2x

1.5A. 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.

One of the LDOs supports an output current of 400mA

at an output voltage range of 0.6V to 3.4V. The LDO

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

allow voltage-changes during operation. The other

LDO supports an output current of 300mA at an

output voltage range of 1.2V to 3.3V. The LDO also

supports load-switch mode.

The I2C-interface, IOs, GPIOs and multi-function-pins

(MFP) allow a seamless interface to a wide range of

SoCs.
