Apparatus and methods to parallelize transistors

Abstract:

Methods, apparatus, systems and articles of manufacture are described to parallelize transistors. An example apparatus includes a first transistor on a first die and a second transistor on a second die. The example apparatus includes a parallel feedback terminal coupled to the first die and the second die and a current sensor including a first contact and a second contact. The example apparatus includes a resistor coupled to the current sensor and at least one of the switched terminal or a ground terminal. The example apparatus includes an active drive controller including a first input coupled to the resistor, a second input coupled to the parallel feedback terminal, and an output coupled to the parallel feedback terminal. The example apparatus includes an edge delay controller adapted to be coupled to a gate driver and an error amplifier, and a control contact adapted to be coupled to the gate driver.
