2.3.1 TPS6521940 - Power Management IC

The TPS6521940 device is a Power Management IC (PMIC) specifically design to support Arm Cortex processors like the i.MX 93 from NXP. The PMIC is a good fit for applications powered from a 5V supply or a Li-Ion battery. The device consists of three synchronous step-down (buck) converters and four linear regulators. The DC-DC converters are capable of 1 x 3.5A and 2 x 2A. 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.

The power and control pin connections between the PMIC and the processor are shown in Figure x.
