TPS75933KTTR is suitable for hard switching applications with low noise, low EMI and high efficiency. Its advanced circuit design technology guarantees a high ESR load transient response, peak current capability and fast load and line regulation.

Working Principle of TPS75933KTTR

TPS75933KTTR is based on the popular topology of an active-clamp forward converter, which is a high-efficiency topology that uses two MOSFETs and a primary side PWM controller to convert and control the DC input voltage to the required output voltage. It is designed to withstand a wide range of input voltage and current levels, while still delivering high efficiency. The primary-side PWM controller in the TPS75933KTTR enables the frequency of the energy-transferring operation to be adjustable according to your requirement, and provides an accurate and reliable output voltage level.

The TPS75933KTTR is designed with a number of advanced features to ensure highly reliable operation: the low output voltage is protected by an Under-Voltage Lockout circuit; input voltage is protected from overvoltage with an overvoltage protection circuit; and input and output overcurrent protection is provided.

In addition, the TPS75933KTTR is also designed with an over-temperature protection circuit that shuts down the regulator\'s operation when the junction temperature exceeds the specified temperature limit. This tightly integrated package helps reduce the number of external components and its efficiency is high, thus achieving cost savings.

Conclusion

The TPS75933KTTR is a highly integrated low input voltage linear regulator power management solution to meet high demands of the Industrial and Automotive Grade Power Management Solutions. Its advanced circuit design technology ensures excellent ESR load transient response, peak current capability and fast load and line regulation. The integrated over-temperature protection circuit helps provide safe and reliable operation.
