The UC2901DTR by Texas Instruments is an integrated circuit designed to provide an isolated feedback loop for power systems. It functions as an isolated feedback generator, offering a stable and reliable alternative to optical couplers.
This device features an internal 1% reference and error amplifier, along with an internal carrier oscillator usable up to 5MHz. It operates over a wide voltage range of 4.5V to 40V and has a typical current consumption of 5mA. The operating temperature range is from -40°C to 85°C.
The UC2901DTR is housed in a 14-SOIC package, suitable for surface mount applications. Its design allows for amplitude modulation to couple loop error signals across an isolation boundary using a small RF transformer or capacitor. It can also be synchronized to an external clock, making it adaptable for various SMPS designs.
Key features include a loop status monitor and outputs that are disabled until the input supply reaches a sufficient level for proper operation. This IC is a low-cost solution for closing feedback control loops across voltage isolation boundaries.
