Working Principle

The TPS60132PWPR utilizes an active voltage scaling technique to reduce external component count. This technique takes advantage of the power MOSFETs inherent losses by running them at lower voltage, while still regulating the output. As a result, the TPS60132PWPR is able to deliver higher efficiency without increasing the switching speed. The TPS60132PWPR has a wide operating frequency range, from 4kHz to 2MHz.

In order to maintain the output voltage, the TPS60132PWPR uses an internal feedback loop that compares the output to the internal reference voltage. When the output voltage is higher than the reference voltage, the switching FETs will be turned off, reducing the power to the output. On the other hand, when the output is lower than the reference voltage, the FETs will be turned on, increasing the power to the output. This feedback loop is used to maintain the output voltage regardless of changes in load current.

Conclusion

The TPS60132PWPR is an advanced DC-DC switching regulator series with high power and low cost. It is designed to meet the requirements of a variety of applications in automotive, industrial, medical, and consumer markets. It supports a wide input voltage range of 2.25V to 20V and utilizes an active voltage scaling technique to reduce external component count and dramatically increase power. The TPS60132PWPR has a wide operating frequency range, from 4kHz to 2MHz, and utilizes an internal feedback loop to maintain the output voltage.
