Background
The TPS65261 PMIC is a triple 3-A, 2-A, 2-A output current, synchronous step-down (buck) converter with
an operational range of 4.5 V to 18 V. The TPS65261 features an automatic power sequence with
connecting MODE pin to V7V and configuring EN1/2/3 pins. The device also features an open drain
RESET signal to monitor power down. The TPS65261 operates in pulse skipping mode (PSM) light load.
As there are many possible options to set the converters,
Table 1
presents the performance specification
summary for the EVM.
