Guangdong core source (GS / SC) introduced a high-performance intelligent switch controller ICs current mode, designed for small appliances control board power and other non-isolated offline and dc-to-dc switched mode buck converter design. Complete internal integration of PWM / PFM hybrid control circuit voltage up to 700V power switching circuit, fault detection and protection circuit, clock delay control circuit, at 85-380Vac of wide grid voltage conditions, with no less than 400mA (GS50030) / 200mA (GS50015) of rated output current capability. Improve the internal circuit design minimizes 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 at the circuit in electrical yo continuous mode without switching conditions, with a high efficiency transfer arrived, according to the different requirements of the output characteristics of the circuit can be flexible to work in a different connection structure, so as to facilitate to achieve a positive or negative voltage output to drive a relay or SCR circuit adapt to different requirements. An on-chip having a maximum time limit function clock generation circuit, with the leading edge blanking by-cycle current limiting circuit, the thermal switch circuit with hysteresis characteristics, 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 efficiency, make the machine easy to meet countries' energy efficiency standards.
