TPS62080EVM-641

1.2A, High-Efficiency, Step-Down Converter Evaluation Module

The is an evaluation module for TPS62080, 1.2A, high efficiency, step down converter. The TPS6208x focuses on high efficiency, step down conversion over a wide output current range. At medium to heavy loads, the converter operates in PWM mode and automatically enters PFM or power Save mode operation at light load currents to maintain high efficiency over the entire load current range. To maintain high efficiency at very low load or no load currents, a snooze mode with an ultralow quiescent current 5µA is implemented, which maintains the output voltage. This function increases the run time of battery driven applications and keeps the standby current at its lowest level to meet green energy standards targeting for a low standby current. To address the requirements of powering supply rails, the internal compensation circuit allows a large selection of external output capacitor values ranging from 10µF up to 100µF.
