Description

2. Background. The TPS65251 PMIC is designed to provide 3-A and 2-A continuous outputs with an operational range of. 4.5 V to 18 V and an externally set switching frequency ranging from 300 kHz to 2.2 MHz. When the PMIC is not fully loaded, Buck1 can be loaded to 3.5 A and Buck2 and Buck3 to 2.5 A. As there are The TPS65250, TPS65251 , TPS65252, and TPS65253 family of power management ICs provides easy to use, flexible, 2xDCDC and 3xDCDC configurations. In order for the converters to perform optimally, certain layout rules should be followed. Passive components should be placed as close as possible to their respective Number. Revision. Size. A4.
