Apparatus and methods for voltage converters

A bypass circuit for a voltage converter including an inductor and a plurality of switches configured to control a current through the inductor, the bypass circuit comprising:

• a first p-type field effect transistor (PFET) transistor;
• a first n-type field effect transistor (NFET) transistor having a drain electrically connected to a source of the first PFET transistor and to a first end of the inductor;
• a second PFET transistor having a source electrically connected to a drain of the first PFET transistor;
• and
• a second NFET transistor having a drain electrically connected to a source of the first NFET transistor and a source electrically connected to a drain of the second PFET transistor and to a second end of the inductor.

A wireless device comprising:

• a battery having a battery voltage;
• a voltage converter including an inductor and a plurality of switches configured to control a current through the inductor, the voltage converter configured to generate a plurality of output voltages from the battery voltage;
• and
• a bypass circuit including a first p-type field effect transistor (PFET), a second PFET, a first n-type field effect transistor (NFET), and a second NFET, the first and second NFET transistors and the first and second PFET transistors electrically connected between a first end and a second end of the inductor such that a source of the first PFET transistor and a drain of the first NFET transistor are electrically connected to the first end of the inductor and such that a drain of the second PFET transistor and a source of the second NFET transistor are electrically connected to the second end of the inductor.
