Abstract
A complete power management system implemented in a single surface mount package. The system may be drawn to a DC to DC converter system and includes, in a leadless surface mount package, a driver/controller, a MOSFET transistor, passive components (e.g., inductor, capacitor, resistor), and optionally a diode. The MOSFET transistor may be replaced with an insulated gate bipolar transistor, IGBT in various embodiments. The system may also be a power management system, a smart power module or a motion control system. The passive components may be connected between the leadframe connections. The active components may be coupled to the leadframe using metal clip bonding techniques. In one embodiment, an exposed metal bottom may act as an effective heat sink.
