TPS60110PWPG4 is a PMIC – Voltage Regulators – DC DC Switching Regulator which is manufactured by Texas Instruments for use in a variety of applications. The device is a dual-output voltage regulator with a wide range of operating frequency from 200kHz to 2MHz. It is capable of supplying up to 4A load current at each output and is rated for a total output power of 40W. It is a high current, ultrahigh-efficiency, dual-output synchronous buck regulator specifically designed for low voltage systems where board space and efficiency are prime concerns.

The TPS60110PWPG4 is a buck regulator with integrated Pulse-Width Modulation (PWM) controller, high-side and low-side power FETs, output voltage feedback and loop compensation networks, as well as input voltage sensing. The device is easy to use with user-defined programming of voltage and current limits, overvoltage protection, and thermal foldback. It features an adjustable frequency up to 2.0 MHz, allowing reduction of external component size and the use of smaller trace and plane capacitors, ideal for limited board space.

The TPS60110PWPG4 has a wide operating temperature range of -40°C to 105°C and is available in standard 6-lead SOT23 package for optimized size and space. It is ideal for battery-powered systems and applications such as smart phones, tablets, storage devices, powerbanks, and medical systems & applications.

Applications of the TPS60110PWPG4 include:

• Smart phones & tablets
• Portable media players
• Portable storage devices
• Powerbanks
• Medical systems

The working principle of the TPS60110PWPG4 is as follows. The device uses an internal PWM controller to convert an input voltage to an output voltage. The input voltage is sensed by a resistor divider, which sends the signal to the PWM controller. The PWM controller then adjusts the switching frequency to maintain the output voltage. In addition, the output voltage is monitored and compared with the reference voltage by the internal feedback loop. The error signal is used to control the switching frequency and maintain the desired output voltage.

The device\'s PWM controller contains an oscillator, a pulse width modulator, and an error amplifier. The oscillator sets the switching frequency, while the pulse width modulator adjusts the duty cycle of the output signal. The error amplifier senses the difference between the reference voltage and the output voltage, and this signal is used to adjust the switching frequency and maintain the desired output voltage.

To protect against overcurrent and overtemperature, the TPS60110PWPG4 has an adjustable OCP and up to 5°C/W thermal foldback. Also, the device has adjustable overvoltage protection and enable/disable functions. The enable/disable function allows the device to be put into a low-power standby mode. This ensures that the device consumes very low power when not in use and preventing excessive power dissipation.

In summary, the TPS60110PWPG4 is a high current, ultrahigh-efficiency, dual-output synchronous buck regulator specifically designed for low voltage systems. It is ideal for battery-powered systems and applications such as smart phones, tablets, storage devices, powerbanks, and medical systems & applications. With its adjustable frequency, adjustable output voltage, adjustable overvoltage protection, and enable/disable feature, the TPS60110PWPG4 is the perfect solution for applications that require a small size footprint and high efficiency.
