Disclosed is a helmet provided with a radar reflector. The helmet includes a helmet body formed in a shape corresponding to a shape of a user head, and the radar reflector mounted on an outer surface of the helmet body to reflect a radar signal transmitted from radar equipment. The radar reflector includes a plurality of reflection units each concaved in a trigonal pyramid shape having one opened surface, each of the plurality of reflection units reflecting the radar signal. Thus, by applying the radar reflector to the helmet of a user aboard an object to be detected by using a radar signal, the radar signal is effectively reflected in bad weather or at night, thereby improving the recognition rate of radar equipment.

A synchronous direct current (DC)-DC buck converter and a method of controlling the waveforms of switching signals disclosed herein. The synchronous DC-DC buck converter generates a stepped-down output voltage using a first switch configured to apply an input voltage to an inductor and a second switch configured to switch in response to a second switching signal. The synchronous DC-DC buck converter includes a sawtooth generation unit, a driver oscillating signal generation unit, a switching signal generation unit, and a phase tracking unit. The sawtooth generation unit generates a sawtooth wave. The driver oscillating signal generation unit generates an error voltage between the output voltage and a reference voltage, and compares the sawtooth wave with the error voltage, so as to generate a driver oscillating signal. The switching signal generation unit generates each of the first and second switching signals. The phase tracking unit generates the frequency setting signal.
