Summary:
CX75GD080S is a high-frequency and high-performance quasi resonant AC/DC conversion power switch that integrates high-voltage GaNFET power devices. It is applied to a high-performance, low standby power, low-cost, and high-efficiency isolated flyback switching power supply within 27W.
CX75GD080S can operate at a maximum frequency of 200KHZ and can operate in quasi resonant mode throughout its entire range. At light loads, it operates in burst mode to improve efficiency, minimizing tonal energy below 23kHz and eliminating audio noise during operation
CX75GD080S integrates complete protection functions, including Vcc undervoltage protection (UVLO), Vcc overvoltage protection (Vcc_oVP), input undervoltage protection (Brown in), input overvoltage protection (Brown out), output overvoltage protection (VO_oVP), FB short-circuit protection, secondary SR short-circuit protection, CS short-circuit protection, etc.
CX75GD080S provides excellent electromagnetic interference performance, providing a good design platform for cost-effective flyback switching power supply systems that require ultra-low standby power consumption.
