UCG2883x/4x is a high frequency, quasi-resonant flyback converter with a built-in 750V GaN high electron mobility transistor (HEMT) with low Rds(on) for AC to DC power conversion. The UCG2883x/4x is designed for high power density applications, such as cell phone fast chargers and notebook adapters. The key feature of this device is the self-bias and auxless sensing scheme which eliminates the need of the auxiliary winding and simplifies the system design with higher efficiency.
The UCG2883x/4x also features intelligent mode transition (CCM/QR/DCM) to enable high efficiency across a wide power range and <30mW standby power consumption. In addition, UCG2883x/4x includes a full list of protections such as brownin and brownout protection, SCP, OVP, OPP, LPS, OFB, and OTP. The cycle-by-cycle current limit allows for fast response to the fault conditions to safeguard the system and improve the reliability. In a small 5mm × 5mm package, the UCG2883x/4x has dedicated configuration pins to offer more flexibility. Only resistors are needed to tune certain parameters for each system, enabling a platform design with a single device.
