TPS62615 350mA、6MHz、1.2V 输出高效降压转换器
TPS62615 描述
The TPS6261x device is a high-frequency synchronous step-down dc-dc converter optimized for battery-powered portable applications. Intended for low-power applications, the TPS6261x supports up to 350-mA load current, and allows the use of low cost chip inductor and capacitors.
With a wide input voltage range of 2.3V to 5.5V, the device supports applications powered by Li-Ion batteries with extended voltage range. Different fixed voltage output versions are available from 1.2V to 2.3V.
The TPS6261x operates at a regulated 6-MHz switching frequency and enters the power-save mode operation at light load currents to maintain high efficiency over the entire load current range.
The PFM mode extends the battery life by reducing the quiescent current to 31µA (typ) during light load operation.
