Summary:
CX75GD025E 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 45W.
CX75GD025E can operate at a maximum frequency of up to 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.
CX75GD025E 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.
CX75GD025E provides excellent electromagnetic interference performance, providing a good design platform for high cost performance flyback switching power supply systems that require ultra-low standby power consumption.
