A switching regulator may include; an inductor connected to a switch node, a power switch connected to the switch node and configured to apply a first voltage to the switch node in response to a first control signal and to apply a second voltage to the switch node in response to a second control signal, and a controller configured to generate the first control signal and the second control signal. The second control signal transitions from low to high following a first dead time after the first control signal transitions from low to high, the first control signal transitions from high to low following a second dead time after the second control signal transitions from high to low level, and an inductor current flowing through the inductor flows in a first direction during the first dead time and in a second direction, different from the first direction, during the second dead time.

Switching regulator and power management integrated circuit

A signal generation circuit includes: a clock signal generator configured to generate a clock signal and to change a frequency of the clock signal in response to a select signal; a transmission control circuit configured to control transmission of the clock signal based on the select signal; and a counter configured to perform an operation among a count operation and a count stop operation based on an output signal of the transmission control circuit and to output the select signal based on a result of performing the operation. When the counter performs the count operation in response to the clock signal output from the transmission control circuit, the counter outputs a most significant bit (MSB) among its count bits as the select signal.

Signal generation circuit, method of operating a signal generation circuit, and device for generating an output voltage

A voltage regulator and a memory device including same are provided. The voltage provider includes a resistive circuit configured to output at least one divided voltage; at least one driver circuit configured to be connected to the resistive circuit and to set the at least one divided voltage; and a compensation circuit configured to be connected to the at least one driver circuit, to receive a predetermined voltage, and to apply a power supply voltage to the at least one driver circuit. The at least one driver circuit may set the at least one divided voltage based on the power supply voltage received from the compensation circuit.
