UCG2882x is a high frequency, quasi-resonant flyback converter with a built-in 750V GaN high electron mobility transistor (HEMT) with as low as 170mΩ Rds(on) for AC to DC power conversion. The UCG2882x 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 UCG2882x also features intelligent mode transition (CCM/QR/DCM) to enable high efficiency across wide power range and <30mW standby power consumption. In addition, UCG2882x 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 5 × 5mm package, the UCG2882x 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.
