Semiconductor dice are mounted at the first surface of the die pads. A molding encapsulation material surrounds the semiconductor dice mounted at the first surface of the die pads to produce semiconductor devices, with the semiconductor devices being mutually coupled via the tie bars.

The tie bars have a hollowed-out portion with a channel-shaped cross-sectional profile at the intermediate singulation location. Easier-to-cut tie bars can be provided without impairing their stiffness in comparison with tie bars having full rectangular/square cross-sectional shapes.

Abstract: A control circuit for a switching stage of an electronic converter is described. The control circuit includes a driver circuit configured to generate one or more drive signals as a function of a Pulse-Width Modulation, PWM, signal and a PWM signal generator circuit configured to generate the PWM signal. A first comparator asserts a comparison signal when a feedback signal having a voltage being indicative of a current flowing through an inductance of the switching stage is greater than a reference signal. In response to a clock signal, a storage element asserts the PWM signal, whereby the clock signal indicates the duration of the switching period of the PWM signal. Conversely, in response to determining that the comparison signal is asserted, the storage element de-asserts the PWM signal. Specifically, the reference signal is generated as a function of the voltage at a capacitance.
