The Texas Instruments TPS63900 is a high-efficiency synchronous buck-boost converter with an extremely low quiescent current (75 nA typical) in a 10-pin, 2.5-mm × 2.5-mm, 0.5-mm pitch WSON package.
The TPS63900EVM uses the TPS63900 integrated circuit (IC) and operates with an input voltage up to 5.5 V.
Refer to the TPS63900 data sheet for the full range of recommended operating specifications and design guidelines for driving loads. Table 1-1 provides a summary of the tested TPS63900EVM performance specifications. All specifications are given for an ambient temperature of 25°C.
| SPECIFICATION | TEST CONDITIONS | MIN | TYP | MAX | UNIT |
