Switching circuit and DC-to-DC converter

A DC-to-DC converter comprising:

• a switching circuit including:
• a high-side switch connected between a high potential terminal and an output terminal;
• a rectifier connected between the output terminal and a low potential terminal, forward direction of the rectifier being a direction from the low potential terminal to the output terminal;
• and
• a driver connected between the high potential terminal and the output terminal, the driver switching a high-side switch ON based on an input high-side control signal, the driver switching the high-side switch OFF when a first short detector detecting shorts of the output terminal with the low potential terminal after a first period longer than a backward recovery time of the rectifier until the high-side control signal changing, and
• a controller generating the high-side control signal of a PWM signal based on an input voltage.
