Voltage control circuit
Provided is a voltage control circuit which suppresses a calorific value that generates when short-circuit fault occurs even if a voltage value of an input voltage is large. At the time of short-circuit fault, an additional control voltage Va whose voltage value becomes larger when the voltage value of the input voltage Vin is larger is input to the voltage control p-channel MOS transistor (110) from a transistor control MOS transistor (160), to thereby increase resistance of the voltage control p-channel MOS transistor (110) to suppress a short-circuit current. As a result, when the input voltage Vin is larger, the current value of a holding current or a calorific value after the short-circuit protecting operation has been conducted can be suppressed.

A voltage regulator with current-mode, dual-edge pulse width modulation (PWM) and non-linear control. The voltage regulator may include a top switch (e.g., MOSFET) configured to couple a power supply supplying an input voltage to a load. A linear control circuit of the regulator may use a first ramp signal to control turning ON of the top switch and a second ramp signal to control turning OFF of the top switch. A non-linear control circuit may turn ON the top switch upon detection of a load current step-up change to maintain an output voltage of the regulator within its regulation band. The non-linear control circuit may turn OFF the top switch upon a load current step-down change to prevent output voltage overshoot.
