Texas InstrumentsTPS62080EVM-641电源管理开发电路板和套件

The TPS62080EVM-641 is an evaluation module (EVM) for TPS62080. 1.2-A, 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 (5 μA) 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 10 μF up to 100 μF. The TPS6208x operates at a nominal frequency of 3 MHz. With its DCS-Control™ architecture, excellent load transient performance, and output voltage regulation, accuracy is achieved. The robust architecture and safety features allow perfect system integration. The device is available in 2 x 2-mm package with thermal PAD.
