TPS62135 - Texas Instruments

TPS62135 High Accuracy 3-V to 17-V 4-A Step-Down Converters

The TPS62135 and TPS621351 are high efficiency and easy to use synchronous step-down DC-DC converters, based on the DCS-Control™ Topology. The devices wide input voltage range of 3-V to 17-V makes it suitable for multi-cell Li-Ion as well as 12-V intermediate supply rails. The devices provide 4-A continuous output current. The TPS62135 automatically enters P.
