MAX5021/MAX5022 Current-Mode PWM Controllers for Isolated Power Supplies General Description
... less than the UVLO start threshold, the IC typically consumes only 50µA of quiescent current. This low startup current and the large UVLO hysteresis combined with the use of a ceramic capacitor C2 keeps the power dissipation in RS to less than 1/4W even at the high end of the universal AC input volt ...

Control system
A control system is a device, or set of devices, that manages, commands, directs or regulates the behavior of other devices or systems. Industrial control systems are used in industrial production for controlling equipment or machines.There are two common classes of control systems, open loop control systems and closed loop control systems. In open loop control systems output is generated based on inputs. In closed loop control systems current output is taken into consideration and corrections are made based on feedback. A closed loop system is also called a feedback control system. The human body is a classic example of feedback systems.
