PRODUCTION DATA.
The TPS65216 provides three step-down converters three general-purpose I/Os, one buck-boost converter, one load switch and one LDO. The system can be supplied by a regulated 5-V supply. The device is characterized across a –40°C to +105°C temperature range, which makes it suitable for various industrial applications.
The I2C interface provides comprehensive features for using TPS65216. All rails, the load switch, and GPIOs can be enabled / disabled. Voltage thresholds for the UVLO and supervisor can be customized. Power-up and power-down sequences can also be programmed through I2C. Interrupts for overtemperature, overcurrent, and undervoltage can be monitored for the load-switch.
The integrated voltage supervisor monitors DCDC 1-4 and LDO1. It has two settings; the standard settings only monitor for undervoltage, while the strict settings implement tight tolerances on both undervoltage and overvoltage. A power good signal is provided to report the regulation state of the five rails.
The three hysteretic step-down converters can each supply up to 1.8 A of current. The default output voltages for each converter can be adjusted through the I2C interface. DCDC 1 and 2 feature dynamic voltage scaling with adjustable slew rate. The step-down converters operate in a low power mode at light load, and can be forced into PWM operation for noise sensitive applications.
