Abstract: A voltage convertor module includes a lead-frame, a unitary bare die and a molding body. The lead-frame can have a plurality of electrodes including an input voltage electrode, an output voltage electrode, a ground electrode and a controlling electrode. The unitary bare die is disposed only on the lead-frame, where a plurality of pads of the unitary bare die are electrically connected to the electrodes of the lead-frame correspondingly. The unitary bare die includes the plurality of pads, a buck controller block, a first switching unit block, a second switching unit block, a feedback unit block and a plurality of routing structures.
