Working Principle of TPS92310DGS/NOPB

The TPS92310DGS/NOPB driver IC is based on a boost converter architecture, which helps to reduce energy loss and improve the efficiency of the boost converter. The device is a low-voltage high-current charger, and includes features such as over current protection, thermal shut-down, frequency shifting and soft start. The boost converter is based on two main components: an inductor and a capacitor. The inductor serves as an energy storage unit, storing energy for the charge and providing it during the discharge cycle. The capacitor helps in smoothing the current ripple, providing a more stable output voltage. The device also contains a charge pump circuit and an error amplifier, which reduce the ripple and boost the output voltage.

The current regulation circuit of the TPS92310DGS/NOPB is based on the output voltage. The current is regulated by the output voltage, which is set using the external resistive divider. The operating frequency of the TPS92310DGS/NOPB is set using an external RC network. The operating frequency can be adjusted by changing the value of the external capacitor. The device also has built-in protections such as over-voltage and Short circuit protection, and an adjustable Over-Temperature Protection to protect the LED driver IC from over-heating.

Conclusion

The TPS92310DGS/NOPB is one of the most versatile PMICs for LED drivers due to its capability to operate at high frequency, its low voltage operation, and its wide voltage range. This makes the device suitable for applications such as backlighting in display modules, LED lighting, LED performance lighting, LED automotive applications, LED displays, LED switching, LED dimming, and motor control applications. The device also features protection features such as over-voltage and short circuit protection, adjustable over-temperature protection, and a charge pump circuit for improved current regulation.
