KP22062
KP22062 High-frequency, high-performance quasi-resonant mode ACDC power switch integrating GaN FET KP22062 is a high-frequency, high-performance quasi-resonant mode AC-DC converter power switch that integrates a GaN FET. The chip integrates a drive regulation function that can adjust the turn-on speed of the GaN FET to optimize system EMI performance. KP22062 can operate at a frequency of up to 500kHz and operates in quasi-resonant mode across the full range. The chip supports an ultra-wide VDD supply voltage range of 9V-112V. The chip directly detects the AC input voltage and provides a fast start-up function, X capacitor discharge function and standby power consumption of less than 30mW. KP22062 integrates complete protection functions, including: VDD undervoltage protection (UVLO), VDD overvoltage protection (VDD OVP), input undervoltage protection (BOP), input overvoltage protection (LOVP), output overvoltage protection (OVP), cycle-by-cycle current limiting (OCP), abnormal overcurrent protection (AOCP), overload protection (OLP), output overcurrent protection (SOCP), built-in overtemperature protection (OTP), and CS pin open protection. KP22062 uses a small DFN5*6 mm package and is suitable for high-frequency, high-power density, wide input/output range AC-DC converter designs.
