Abstract
A switching pulse generating circuit includes: a load current setting portion to determine the amount of current flowing through a load based on a load current setting signal, the load current setting signal being externally supplied to the load current setting portion, the load current setting signal specifying the amount of current flowing through the load; and a pulse generating portion to output voltage supplying pulses, the output voltage supplying pulses supplying voltage to the load, the pulse width of the voltage supplying pulses being determined based on the load current setting signal.

A switching pulse generating circuit comprising:
- a load current setting portion to determine the amount of current flowing through a load based on a load current setting signal, the load current setting signal being externally supplied to the load current setting portion, the load current setting signal specifying the amount of current flowing through the load;
- and
- a pulse generating portion to output voltage supplying pulses, the output voltage supplying pulses supplying voltage to the load, the pulse width of the voltage supplying pulses being determined based on the load current setting signal.
A regulator comprising:
- a load current setting portion to determine the amount of current flowing through a load based on a load current setting signal, the load current setting portion being connected to an output terminal;
- a voltage output portion to produce voltage based on the output from a pulse generating circuit;
- and
- the pulse generating circuit to output a pulse signal to the voltage output portion, the pulse width of the pulse signal being determined based on the load current setting signal.
A switching pulse generating circuit for controlling a regulated voltage of a switching regulator, the switching regulator having an output switching element and an output terminal connected to a load, the switching pulse generating circuit comprising:
- a load current setting portion to set the amount of current flowing through the load in response to a load current setting signal;
- a pulse generating portion to provide a switching pulse for the output switching element to control the regulated voltage, the pulse width of the switching pulse being responsive to the load current setting signal.
