TPS65219
Integrated power management (PMIC) for Arm® Cortex®- A53 processors and FPGAs
Data sheet
TPS65219
- 3 Buck converters at up to 2.3-MHz non-fixed switching frequency:
- 1x VIN: 2.5 V – 5.5 V; I OUT: 3.5 A; V OUT 0.6 V – 3.4 V
- 2x VIN: 2.5 V – 5.5 V; I OUT: 2 A; V OUT 0.6 V – 3.4 V
- 4 linear regulators:
- 2x VIN: 1.5 V – 5.5 V; I OUT: 400 mA; V OUT: 0.6 V – 3.4 V (configurable as load switch and bypass-mode, supporting SD-Card)
- 2x VIN: 2.2 V – 5.5 V; I OUT: 300 mA; V OUT: 1.2 V – 3.3 V (configurable as load switch)
- Dynamic voltage scaling on all two three buck converters
- Low IQ/PFM, PWM-mode (quasi-fixed frequency)
- Programmable power sequencing and default voltages
- I 2C interface, supporting standard, fast-mode and fast-mode+
- Designed to support systems with up to 14+ rails (2x TPS65219 7 rails each + GPO-controlled external rails)
- 2 GPOs, 1 GPIO, and 3 multi-function-pins
- EEPROM programmability
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 the PMIC an excellent choice 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. The converters require a small 470 nH inductor, 4.7 µF input capacitance, and a minimum 10 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 load-switch, 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. The 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.
