LLC controllers with hybrid hysteretic control

Achieve enhance load transient response with minimal output capacitance.

The LLC scales to high power output levels. Complexity, efficient operation in light load conditions and system cost are the traditional challenges associated with this topology. These zero-voltage switching, low-EMI and low-component stress controllers offer excellent audible noise immunity when paired with an optimized PFC and SR controller, even with the most demanding system requirements.

LLC controllers without high voltage driver

Our LLC controllers are resonant converters that are optimized for power ranging from 100-W to 1000-W.
