TPS54560 reference design application circuit:

Figure 1 TPS54560 internal structure diagram

The device survives load dump pulses up to 65V per ISO 7637. Current mode control provides simple external compensation and flexible component selection. The TPS54560 is a 60 V, 5 A, step down regulator with an integrated high side MOSFET.

Figure 2 TPS54560 reference design

The device implements constant frequency, current mode control which reduces output capacitance and simplifies external frequency compensation. The wide switching frequency range is a 60 V, 5 A, step-down (buck) regulator with an integrated high side n-channel MOSFET. Of 100 kHz to 2500 kHz allows either efficiency or size optimization when selecting the output filter components.
