The second circuit that will be discussed is
the top (upper) circuit on the TPS542A50EVM-059 shown in
Figure 2-1. In this circuit, the TPS542A50
converter IC is indicated as U1_2. This circuit has been
designed with a minimal layout area for applications where space
is limited. The default switching frequency is 1.2 MHz, which
allows for the use of smaller output inductance and capacitance.
The converter and all associated components fit inside a 17 mm x
14 mm layout area (238 mm
2) while still delivering
high performance for space-critical applications.
