TPS62050EVM-234: 3.3V @ 800mA, 2.7 ~ 10V in, Buck

Summary

The Texas Instruments TPS62050 and TPS62052 evaluation modules (EVM) for low-power, high-efficiency, step-down converters help designers evaluate these devices. The EVMs make it possible to evaluate different modes of the devices as well as the device performance.

The TPS6205xEVM is available as the TPS62050 adjustable version set to 3.3 V and the TPS62052 1.5-V fixed version.

The TPS62050EVM can be easily set up to provide any output voltage between 0.7 V to 6 V (or Vin) by adjusting the external resistor divider. Refer to the data sheet (SLVS432) for various fixed voltage options available for the TPS6205x. The TPS6205x has an input voltage range between 2.7 V and 10 V with an output current up to 800 mA.

Any version of the TPS6205x can be evaluated by removing and replacing the IC on the EVM.
