SLVAEB1A March 2020 – October 2021 TLV62568 , TLV62569 , TLV62585
This application report compared the performance of a 5-V/2-A DC/DC converter (TLV62569) in three different packages: SOT23-5 (DBV), SOT23-6 (DDC), and SOT563 (DRL).
While SOT23-5 (DBV) is widely used since many years, newer packages using FCOL technologies like SOT23-6 (DDC) and SOT563 (DRL) offer multiple advantages depending on the key requirements of the application. For thermal critical applications where the solution size is not the key limiting factor, the SOT23-6 (DDC) package offers the coolest solution between the three packages. For applications where solution size matters the most, the SOT563 (DRL) package offers the smallest size with best light load efficiency among the three packages, without compromising thermal performances and cost.
