The UC1901J from Texas Instruments is an Isolated Feedback Generator that utilizes an amplitude modulation system for transformer coupling of isolated feedback error signals. This device serves as a cost-effective replacement for optical couplers in power systems.
Key features include an internal carrier oscillator usable up to 5MHz, an internal 1% reference, and an error amplifier. The modulator can be synchronized to an external clock, allowing for integration with system clocks or SMPS switching frequencies. A loop status monitor provides an active-low output when the sensed error voltage is within ±10% of the reference.
The UC1901J family supports a wide input supply voltage range of 4.5V to 40V. It is available in DIL-14 and SOIC-14 package types, suitable for surface mount applications.
This component is designed to solve challenges in feedback control loops across isolation boundaries, offering stable and reliable performance for line-operated power systems.
