TPS60110PWPRG4 is a DC-DC switching regulator which is a type of voltage regulator used in many modern integrated circuits. It is a highly efficient, fully integrated, cost-effective, and reliable power management solution. The TPS60110PWPRG4 has a wide range of features including adjustable output voltage, low input voltage range, flexibility in output current capability, protection features and low quiescent current. The voltage regulator is used in various applications such as battery-powered devices, audio-visual systems, automotive systems, and medical equipment.

Overview

The TPS60110PWPRG4 is a triple-output (Vo1, Vo2, Vo3) DC-DC switching voltage regulator. It provides an adjustable output voltage from 0.95V to 6.3V, adjustable current limit settings of 500mA and an adjustable soft-start ramp-up time. The device contains an internal high-side and low-side switch with an external HV-LNB switching node, providing a regulated output at Vo1, Vo2, or both. The enable input (EN) and low-voltage enable input (LVEN) can be controlled externally or used as logic reference voltage. Additionally, power-on reset is included with a level shunt selectable between 0.95V or 2V. An external compensation network is also provided to compensate the internal error amplifier.

Application Field and Working Principle

The TPS60110PWPRG4 is suitable for a wide range of applications, including, but not limited to, portable audio devices, automotive systems and medical equipment. It is designed for use in portable power-supply applications, where the power source is provided by a battery, and the load is a portable device such as a digital audio player. In such a system, the TPS60110PWPRG4 provides the regulated voltage required by the device while consuming a minimal amount of power. The device can also be used in automotive, lighting and medical applications, where adjustable outputs and low quiescent current are critical.

The TPS60110PWPRG4 DC-DC Switching Voltage Regulator works by using an internal high-side, low-side switch and a compensation network connected to an error amplifier. The external input voltage is represented by Vin and the load current is represented by IL. The internal switching circuit charges the output capacitors to the desired voltage and then maintains the output voltage by producing a control signal and providing it to the error amplifier. The error amplifier is a feedback loop which compares the output voltage to the desired voltage and then adjusts the duty cycle of the internal switch accordingly.

Features

The TPS60110PWPRG4 provides many features designed to provide a reliable and highly efficient power management solution. These features include: adjustable output voltage range of 0.95V to 6.3V; adjustable current limit settings of 500mA; adjustable soft-start ramp-up time; enable input (EN) and low-voltage enable input (LVEN) can be used as logic reference voltage; power-on reset with level shunt selectable between 0.95V or 2V; and built-in over-temperature protection.

Conclusion

The TPS60110PWPRG4 is a highly efficient and cost-effective DC-DC switching voltage regulator which provides a reliable and convenient way to regulate the output voltage of a range of different applications such as portable audio devices, automotive systems, and medical equipment. It has many features such as adjustable output voltage range, adjustable current limit settings, adjustable soft-start ramp-up time, enable input, power-on reset and built-in over-temperature protection.
