Title: Switching regulator
Inventor: UMEMOTO SEIKI
IPC: H02M3/155
Filed: 2001-04-18
Abstract: PROBLEM TO BE SOLVED: To provide a switching regulator having high voltage stability operating speed, capable of performing regulation for voltage obtained from a high input DC power supply by generating a control pulse with low voltage. SOLUTION: This regulator performs switching control for an output stage MOS transistor on a Hi side by generating a control pulse with low voltage, and by converting it to the control pulse having fast rise and fall at high voltage with a level shift circuit. The level shift circuit is constituted of a comparator. A medium level between 'H' and 'L' levels of a first control pulse, which serves as its reference value, is compared with the first control pulse for obtaining outputs of 'L' or 'H' respectively, at a point when the level of the first control pulse exceeds a reference level or when it becomes lower than the reference level. Therefore, the rise and fall of an output signal become fast. Especially, by using a current switch circuit as the comparator, a through rate becomes large, thus it is possible to shorten the rise and fall time.
