MAX5035参考设计应用电路：

图1MAX5035内部结构图

TheMAX5035 easy-to-use, high-efficiency, high-voltage,step-down DC-DC converter operates from an input voltage up to 76V and consumes only 270µA quiescent current at no load. This pulse-width modulated (PWM) converter operates at a fixed 125kHz switching frequency at heavy loads, and automatically switches to pulse-skipping mode to provide low quiescent current and high efficiency at light loads.
