Texas Instruments TPS621361RGXR
The TPS62136 and TPS621361 are high efficiency and easy to use synchronous step-downDC-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-cellLi-Ion as well as 12-V intermediate supply rails. The devices provide 4-A continuous outputcurrent. The TPS62136 automatically enters Power Save Mode at light loads to maintain highefficiency across the whole load range. With that, the device is well suited for applications thatrequire connected standby performance, like ultra low power computers. With the MODE pin set tolow, the switching frequency of the device is adapted automatically based on the input and outputvoltage. This technique is called Automatic Efficiency Enhancement (AEE™) and maintains highconversion efficiency over the whole operation range. It provides a 1% output voltage accuracy inPWM mode and therefore enables the design of a power supply with high output voltageaccuracy.
The device has a typical quiescent current of 18 µA. In shutdown mode the current istypically 1 µA and the output is actively discharged for TPS62136 while the output voltagedischarge feature is disabled in TPS621361.
The TPS62136 is available as an adjustable version, packaged in a 3-mm x 2-mm VQFNpackage.
