Description

TIDA-050056 is a 5-V to 17-V input voltage buck converter reference design which is intended for applications that have a very limited design space. Featuring the TPS629210-Q1 buck converter, the reference design steps down the input voltage to 3.3-Vout and is capable of delivering up to 1-A of load with high efficiency and low quiescent current. The inductor used in this design is a 1.5-μH inductor with about 138-mΩ DCR. The total solution size including all external components is 20-mm2. This design delivers highly efficient DC/DC conversion and small solution size with the lowest operating quiescent current (IQ) in the industry. The same design is applicable to the TPS629210 device which is pin to pin compatible with TPS629210-Q1.
