The TPS60141PWPR is a DC-DC switching regulator developed by Texas Instruments. This voltage regulator is part of the PMIC (Power Management IC) voltage regulators family and it belongs to the DC DC switching regulators subcategory. The TPS60141PWPR is especially useful in applications with requirements of low quiescent current, while at the same time they need high efficiency and small output voltage noise.

The key features of this IC include differential remote sense, adjustable input undervoltage protection, adjustable output voltage, adjustable switching frequency, output overvoltage protection, output current and temperature monitoring and programmable power on/off sequencing. The output current can be adjusted from 1mA up to 1.1A. Due to its high-performance integrated architecture, the TPS60141PWPR is suitable for a wide range of applications, particularly those requiring space saving and high efficiency.

The operating temperature is from -40°C to +125°C and the voltage range is from 2.5V to 6V. Its quiescent current is typically 0.1mA while under light load and its switching frequency is typically 1.2MHz. The accuracy of the output voltage is around ±1.25%. The parts are also RoHS and Green compliant and also have a reliable feature set with approvals and markings which enables a fast market time.

The TPS60141PWPR integrated circuit works as a current mode synchronous PWM (pulse width modulation) regulator. To control the output voltage an external feedback voltage is needed plus an external circuit to perform the loop compensation of the feedback signal. The switching frequency and current limit can also be externally programmed, allowing more flexibility and performance.

When this ICs is enabled, the oscillator starts to run and then a sawtooth waveform is generated. When the comparator output voltage exceeds the feedback voltage the PWM is cleared and the output is turned off. During the PWM off time, the inductor current flows to the load and the output voltage is controlled. Whenever the PWM signal reoccurs the output voltage is set to the original value.

In summary, the TPS60141PWPR is a high-performance integrated circuit suitable for a wide range of applications. This component is able to provide a constant output voltage with a high accuracy of ±1.25%. The internal switching mechanism limits the quiescent current with a minimum of 0.1mA while the switching frequency of 1.2MHz provides the needed efficiency. Additionally the IC is RoHS and Green compliant enabling a fast market time with the needed approvals and markings.
