TPS61106PWRG4

The TPS61106PWRG4 is a power management integrated circuit (PMIC) from Texas Instruments that provides a linear + switching voltage regulator. It is designed for high-power, high-efficiency applications such as those found in mobile phones and computers. The device is able to deliver up to 6A of current with a wide input voltage range of 2.7V to 5.5V.

Application Field

The TPS61106PWRG4 is ideal for uses in mobile devices such as smartphones, tablets, and notebooks as it is able to perform efficient and low power-dissipating voltage regulation at loads up to 6A. It can also be used in non-mobile applications such as automotive, industrial control, power management, and even medical applications, due to the wide input voltage range and output current capability.

Working Principle

The TPS61106PWRG4 operates on a linear + switching regulator principle. It uses a pulse-width modulation (PWM) controller with a high-side MOSFET and a low-side p-channel MOSFET for controlling the output voltage. During light loads, the device operates in linear mode using a series pass regulator. When the load increases beyond a certain point, the IC transitions to switching mode to increase efficiency. Switching mode operation is provided by a pulse-width modulation (PWM) phase-shift controller.

The device features six different power-up sequences and includes a unique soft start feature which allows the current sourcing and sinking capabilities of the device to control the timing of power-up sequences. The IC also includes several protection features such as over-current protection (OCP), over-voltage protection (OVP), short-circuit protection (SCP), and thermal shutdown (TSD).

The TPS61106PWRG4 is a power-efficient and feature-rich PMIC that is ideal for applications that require a wide input voltage range and a high output current capability. It is designed for mobile devices, but can also be used in non-mobile applications such as automotive, industrial control, and medical applications.
