Intelligent power module packaging structure

Abstract

An intelligent power module packaging structure includes an insulated heat dissipation substrate, a plurality of power devices, a control chip, a lead frame, and an encapsulant. The insulated heat dissipation substrate has a first surface and a second surface opposite to the first surface. The power devices are disposed on the first surface. The control chip is disposed on the first surface. The control chip provides a gate driver function for driving the power devices and a pulse width modulation function. The lead frame is bonded onto the first surface. The power devices are electrically connected to the control chip and the lead frame. The encapsulant at least encapsulates the power devices, the control chip, and a portion of the lead frame, and the second surface is entirely or partially exposed outside the encapsulant.

Dependencies are inferred from the claim text.
