A sliding mechanism for portable electronic device includes a sliding housing, a main housing and a stopping module. The sliding housing includes two ledges. At least one of the ledges defines a first notch and a second notch. The main housing includes two rails and at least one elastic member. The sliding housing is slidingly attached to the main housing by engagement of the ledges and the rails. The at least one elastic member includes a positioning portion. The positioning portion flexibly resists the at least one of the ledges and is selectively engaged in the first notch and the second notch. The stopping module prevents the sliding housing from separating from the main housing.

The present technology discloses a switching mode power supply with predicted PWM control. In one embodiment, the switching mode power supply monitors the slew rate of COMP signal which represents the output voltage of the switching mode power supply. When the load steps up, the ON state of the power stage is prolonged; when the load steps down, the power stage is turned off earlier.

A shielding can (100) includes a shielding case (10) configured to reducing electromagnetic interference, and a cushion (20) integrally mounted to the shielding case by insert molding. The cushion is configured to absorb shock force. A method for making the shielding can includes the following steps: providing a mold; placing a shielding case in the mold; injecting shock absorbing material into the mold to form a cushion on the shielding case; cooling the molded shielding can; and removing the shielding can from the mold.
