VOLTAGE BOOSTER AND METHOD FOR MAKING RESERVATION OF BOOSTING REQUEST

摘要

A boosting device and method for reserving a boost request is disclosed. In the boosting device, the latch circuit activates the pulse generation request signal in response to the boost request signal, checks whether there is a next boost request signal reserved in response to the boost cycle signal, and selectively selects the pulse generation request signal according to a check result. Activate or deactivate A pulse generator generates a plurality of boost drive pulses in response to the pulse generation request signal, and a cycle signal generator generates the boost cycle signal in response to a last one of the plurality of boost drive pulses. The boost generator generates a boost by boosting a predetermined power supply voltage according to the plurality of boost driving pulses.
