TPS54561参考设计应用电路：

图1TPS54561内部结构图

TheTPS54561 is a 60-V, 5-A, step down regulator with an integrated high side MOSFET. The device survives load dump pulses up to 65V per ISO 7637。Current mode control provides simple external compensation and flexible component selection.

图2TPS54561参考设计图

TheTPS54561 is a 60-V, 5-A, step-down (buck) regulator with an integrated high side n-channel MOSFET. The device implements constant frequency, current mode control which reduces output capacitance and simplifies external frequency compensation.
