Texas InstrumentsTPS82672EVM-646Power Management Development Boards and Kits

The TPS82672EVM-646 is a fully assembled and tested platform for evaluating the performance of the TPS82672 high-frequency, synchronous, step-down dc-dc converters optimized for battery-powered portable applications. The TPS82671, TPS82672, TPS82675, TPS82690 and TPS82695 devices are series of high-frequency, synchronous, step-down dc-dc converters optimized for battery-powered portable applications. Intended for low-power applications, the TPS8267x support up to 600-mA load current and the TPS8269 support up to 500-mA and all allow the use of low-cost chip inductors and capacitors. With a wide input voltage range of 2.3 V to 4.8 V, the devices support applications powered by lithium-ion (Li-Ion) batteries with extended voltage ranges. Different fixed voltage output versions of the TPS826xx are available. These converters operate at a regulated 5.5-MHz (TPS8267x) and 4-MHz (TPS8269x) switching frequency and enter a power-save mode operation under light load currents in order to maintain high efficiency over the entire load current range. A PFM mode extends the battery life by reducing the quiescent current to 17 μA (typ) during light load operation
