POWER-SUPPLY DEVICE, IC CIRCUIT, AND INFORMATION PROCESSING APPARATUS, AND SOFT-START CONTROL METHOD |
| 摘要 |
An electric current flowing to an upper side power MOSFET during soft-start is detected according to an on-voltage of the MOSFET and an on-pulse width of a PWM pulse for driving the upper side power MOSFET is forced to be reset in the idle and decided according to a signal generated when the voltage falls below a predetermined specified voltage.
