The TPS55288 integrates two 16-A MOSFETs of the boost leg to balance the solution size and efficiency for USB Power Delivery (USB PD) application. The TPS55288 has up to 36 V input voltage capability. It can output 15 A when working in buck mode. When working in boost mode, the device delivers 100 W from 8 V input or 60 W from 5 V input. When the input is a single cell Li-ion battery, th...
