Abstract
Power source voltage is supplied to a boost driver of a booster circuit. The boost driver generates a pulse signal when a boost-starting signal indicative of start of boost is input. A boost capacitor boosts voltage level of an output terminal when the pulse signal is received. A precharge circuit supplies voltage to the output terminal on standby before boosting. A constant-voltage generating circuit supplies constant voltage to the precharge circuit.
Claims8
A booster circuit, comprising:
- an output terminal;
- a boost driver to which power source voltage is supplied, said boost driver generating a pulse signal when a boost-starting signal indicative of start of boost is input;
- a boost capacitor which boosts voltage level of said output terminal when said pulse signal is received;
