Abstract: A control device (2) is provided. The control device (2) operates in cooperation with together with a packaged electronic component (1) and a circuit board (3). The packaged electronic component (1) includes a predetermined contact pad array (10) having a plurality of first contact pads (A11-A33), the circuit board (3) includes a plurality of conductive vias (Cll-C43) passing through the circuit board (3), and the conductive vias (C11-C43) includes a plurality of first conductive vias (C11-C33) arranged corresponding to the first contact pads (A11-A33). The control device (2) includes a signal contact array (20) including a plurality of first signal contacts (B11-B33). When the control device (2) is disposed on one side of the circuit board (3) and the packaged electronic component (1) is disposed on another side of the circuit board (3), the control device (2) at least partially overlaps with the packaged electronic component (1) in a thickness direction of the circuit board (3), and each of the first signal contacts (B11-B33) is electrically connected to the corresponding one of the first contact pads (All-A33) via the corresponding one of the first conductive vias (C11-C33).

Abstract: A power supply circuit includes a first regulator and a second regulator. The first regulator is configured to generate a first output signal according to an input signal. A voltage value of the first output signal decreases according to the input signal and a first voltage threshold value at a power-off stage. The second regulator is configured to be enabled according to the first output signal to generate a second output signal according to the input signal. A voltage value of the second output signal decreases according to the input signal and a second voltage threshold value at the power-off stage. The second voltage threshold value is greater than the first voltage threshold value.

Abstract: A control device (1) and a circuit board (2) are provided. The control device (1) can cooperate with the circuit board (2), and includes a ball grid array (10). The ball grid array (10) includes a plurality of power balls (PI) and a plurality of ground balls (G1), which are jointly arranged in a ball region (10R). The power balls (P1) and the ground balls (G1) are respectively divided into a plurality of power ball groups (101, 101') and a plurality of ground ball groups (100). One of the ground ball groups (100) includes two ground balls (G1) and is adjacent to a power ball group. A ball pitch (d1) between the two ground balls (G1) is greater than that between one of the power balls (P1) and one of the ground balls (G1) adjacent to each other. The circuit board (2) includes a contact pad array (200) corresponding to the ball grid array (10) of the control device (1) so that the control device (1) can be disposed on the circuit board (2).
