Product Details

Flyback Controller, Current Control, UC18/UC28/UC38 Series, Texas Instruments

The isolated-flyback power supply controller provides Constant-Voltage (CV) and Constant-Current (CC) output regulation to improve transient response to large load steps. Primary-Side Regulation (PSR) eliminates the need for an Optocoupler.
