3 Description
The TPS6522005-EP 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 -55°C to +125°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 3.5 A and
2x 2 A. The converters require a small 470 nH
inductor, 4.7 μF input capacitance, and a minimum
10 μF output capacitance per rail depending on the
switching mode configuration.
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.
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.
