Claim Text:
1. An electrostatic discharge (ESD) protection device for an integrated circuit (IC) with a DC-DC converter comprising a high-side switch and a low-side switch coupled in series to the high-side switch, the ESD protection device comprising: a first ESD protection component having a gate electrically coupled to a gate of the high-side switch; and a second ESD protection component having a gate electrically coupled to a gate of the low-side switch; wherein the first ESD protection component is turned on before the high-side switch is able to function and the second ESD protection component is turned on before the low-side switch is able to function; wherein a parasitic capacitor of the first ESD protection component is less than a parasitic capacitor of the high-side switch and a parasitic capacitor of the second ESD protection component is less than a parasitic capacitor of the low-side switch.
