Flyback Controller, Voltage Control, 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.

For these non-cancellable (NC), and non-returnable (NR) products, Terms and Conditions apply.
