Summary:

CX75GD015E 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 65W.

The working frequency of CX75GD015E can reach up to 200KHZ, and it can work in quasi resonant mode throughout the entire range. When in light load, it will work in burst mode to improve efficiency, minimizing tonal energy below 23kHz, and eliminating audio noise during operation.

CX75GD015E 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.

CX75GD015E 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.

Characteristic:

  • Built-in high-voltage GaNFET power device

  • Wide Vcc working voltage: DC9V-40V

  • Up to 200kHz switching frequency

  • Proprietary soft start circuit can reduce secondary Vds stress

  • Built-in input overvoltage and undervoltage protection

  • Built-in output overvoltage protection

  • Built-in Vcc overvoltage and undervoltage protection

  • Built-in OPP/SSCP protection

  • Built-in pin open short circuit protection

  • Support external OTP settings for protection

  • Supporting PPS wide range output

  • ESOP-10W packaging

Application:

  • Switching AC-DC power supply

  • Intelligent small household appliances

  • PC peripheral power supply equipment

  • Laptop auxiliary power supply
