SLUSD12A – OCTOBER 2017 – REVISED FEBRUARY 2018 UCC28780 High Frequency Active Clamp Flyback Controller
1 Features 3 Description UCC28780 is a high-frequency active-clamp flyback
controller that enables high-density AC-to-DC power
supplies that comply with stringent global efficiency
standards such as DoE Level VI and EU CoC V5
Tier-2. User programmable advanced control law
features allow performance to be optimized for both
Silicon (Si) and Gallium Nitride (GaN) power FETs.
Direct operation with switching devices that combine
driver and GaN FETs is further enhanced with logiclevel gate signals and enable outputs. Full and Partial Zero Voltage Switching (ZVS) of
Primary FET with Adaptive Control
Programmable Timing for External Si or GaN
FETs
High Switching Frequency up to 1 MHz
Programmable Adaptive Burst Control and
Standby Mode for Light-Load Efficiency with Low
Output Ripple and Audible Noise Mitigation …
