Working Principle

The TPS610994YFFT operates in a type of constant-frequency, peak current-mode architecture. This means that the switching frequency is kept constant while peak values of the regulator current are measured and kept to a desired level. Any oscillations in the output voltage due to external load variations are detected in the feedback loop and compared to a reference voltage. The difference in output voltage and reference voltage is fed to a timing generator, which controls the switching frequency of the power converter.

The regulator also employs a sync-lock feature, which allows for synchronization of the output frequency with external clock signals. This can be used to reduce EMI and eliminate any audible noise produced by the regulator, improving overall efficiency.

The TPS610994YFFT also features an integrated power-good pin which can be used to notify a system when the output voltage is out of tolerance. This can be extremely useful in systems where the output voltage is required to remain within an acceptable range.

The device also has an over-current protection feature which detects excessive output current and shuts down the converter in the event of a short-circuit.

Conclusion

The TPS610994YFFT is a highly integrated switching regulator designed for small-footprint mobile applications. The device can operate over a wide input voltage range of 1.8V to 6V, and can output up to 11A of current. It features integrated PWM, power-good, and over-current protection functions, as well as a sync-lock feature which can be used to reduce EMI and improve efficiency. The device is also capable of automatic load-tracking which helps to optimize efficiency at all load currents.
