The present disclosure provides for sequentially turning on a plurality of power conversion modules according to the magnitude of load power at the time of driving the power conversion modules, operating power conversion modules which have already been turned on in an optimum efficiency interval, and providing increased load power through a power conversion module which has been newly turned on.

Power converting device, power management integrated circuit, and method for controlling power converting device

A controller for a multi-level converter compares a first voltage proportional to an input voltage or an output voltage with a second voltage proportional to a voltage of a flying capacitor and adjusting a slope of a ramp signal for generating a pulse width modulation (PWM) signal so that the second voltage follows the first voltage in controlling the multi-level converter.

Controller for multi-level converter and power management integrated circuit

A power supply system for a display apparatus, in which a structure for supplying operating voltages for a display panel is improved, and the power supply system may improve power efficiency by generating operating voltages using a system voltage of a high level.
