The wide core source (GS / SC) introduced a high-performance intelligent switching current mode controller IC, designed for small appliances and other non-isolated power supply control panel off and switch-mode DC-DC buck converter design. Its a complete integrated PWM / PFM hybrid control circuit voltage up to 700V power switching circuit, fault detection and protection circuit, clock delay control circuit, in a wide 85-380Vac grid voltage conditions, with no less than 400mA (GS50030) / 200mA (GS50015) of rated output current capability. Improve the internal circuit design, to minimize the number of external components, with minimal devices to achieve a typical buck BUCK topology switching power supply design, featured a variety of fault protection circuitry, further simplifying the maximum output current capability by current setting pins easily set, next to the electrical circuit is not switching conditions yo continuous mode, with a high transfer efficiency of contact, according to the different requirements of the output characteristics of the circuit is the flexibility in different connection structure, so as to facilitate to achieve positive or negative voltage output to drive a relay or thyristor circuit accommodate different requirements. Chip integration of a function with a maximum time limit of clock generation circuit, with the leading edge blanking by-cycle current limiting circuit, thermal switch circuit with hysteresis, output short circuit and overload protection and restart circuit. Proprietary Enhanced energy saving control circuit, the system has a very low standby power consumption and high conversion efficiency, the machine can easily meet the requirements of the countries energy efficiency standards.
