TOY VEHICLE WITH AN ADJUSTABLE DC-DC SWITCH

摘要

In one embodiment there is a toy vehicle having a low inductance motor powered by a high frequency switched voltage at a frequency high enough to create continuous conduction. The vehicle further includes an H-bridge circuit configured to control a direction of the motor and an adjustable high frequency DC-DC switch configured to convert a supply voltage to an output voltage, lower than the supply voltage, for use by the H-bridge circuit to power the low inductance motor in a forward or reverse direction. In addition, a processor is included and has instructions configured to change the output voltage from the DC-DC switch from a first voltage to a second voltage.
