This power-supply design describes the optimized power management IC (PMIC) to power the AMIC110, AMIC120, AM335x and AM437x processors. The TPS65216 is a single chip, power-IC (PMIC) specifically designed to support the AMIC110, AMIC120, AM335x and AM437x line of processors in line-powered (5V) applications. The device is characterized across a –40°C to +105°C temperature range, making it suitable for various industrial applications.
The TPS65216 is specifically designed to provide power management for all the functionalities of the AMIC110, AMIC120, AM335x and AM437x. The DC/DC converters DCDC1 through DCDC4 are intended to power the core, MPU, DDR memory and 3.3V analog and I/O, respectively. LDO1 provides the 1.8V analog and I/O for the processor. GPIO2 allows for warm reset of the DCDC1 and DCDC2 converters. The I2C interface allows the user to enable and disable all voltage regulators, the load switch, and GPIOs. Additionally, UVLO and supervisor voltage thresholds, power-up sequence, and power-down sequence can be programmed through I2C. Interrupts for overtemperature, overcurrent and undervoltage can be monitored as well.
A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
