TPS6211xEVM-101: 3.3V @ 1.5A, 3.6 ~ 17Vin

Summary

The Texas Instruments TPS62110 is a 1.5-A synchronous step-down converter in a 16-pin QFN package. Both fixed and adjustable output voltage units are available.

The TPS62110EVM-101 uses the TPS62110 adjustable version and is set to 3.3 V output. The EVM operates with full rated performance with an input voltage between 3.6 V and 17 V.

U1 is configured for evaluation of the adjustable output version. This unit is configured for 3.3 V. Resistors R1 and R2 are used to set the output voltage between 1.2 V and 16 V. See the TPS62110 datasheet (SLVS585) for recommended values. The feedforward capacitor C3 may also need to be changed. For more information see the data sheet.
