TPS60101PWPRG4

The Texas Instruments TPS60101PWPRG4 is a high-performance, regulator-based power management integrated circuit (PMIC) designed for compact end products. It is a DC-to-DC automatic switching regulator with a wide operating input voltage range of 3 V to 28 V. This IC has a low quiescent current (0.2 μA in normal operation), programmable output voltage and fast transient response. It is suitable for modems, industrial systems and handheld devices.

Application field

The TPS60101PWPRG4 is suitable for most industrial and consumer applications. It can be used in power management, battery charging and system power. It is mostly used in handheld devices and small industrial systems, as it is suitable for small form factors and has a wide input voltage range. It is also used in computing, modems, portable/wearable devices, LED lighting and automotive.

Working Principle

The TPS60101PWPRG4 is a DC-to-DC automatic switching regulator with a wide operating input voltage range. The input can be up to 28 V. It can be configured to boost, buck, or bypass the input voltage. It also has the ability to switch between the two voltage regulation modes, PWM and linear. It can switch between these two regulation modes based on the input voltage and the output current load. It has a low quiescent current making it suitable for low power applications. The output voltage is programmable up to 2.75 V. The fast transient response allows for steady output with accurate and reliable voltage regulation.

The device also has a wide temperature range and a shield over the external terminals to provide protection from high voltage spikes. The smart-low power mode (SLPM) function reduces quiescent current consumption. It also has a compensation loop pin, which can be used to improve the output latency, line regulation, and accuracy of the output voltage. The device also has current limit protection, an under voltage lockout pin, thermal shutdown protection and an inverted output pin for cascading applications.
