The TPS5100IPWRG4 has a high input voltage range of 4V to 14V, allowing it to handle a wide variety of input voltages. It also has a wide output voltage range of 0.5V to 4V, allowing for very tight regulation at the lowest output voltages. The internal logic provides support for PWM, voltage arm assisted adaptive current mode, dynamic frequency control and programmable switching frequency.

The TPS5100IPWRG4 utilizes the latest advanced MOS technologies to deliver high efficiency and low power consumption. It supports a wide input voltage of 4V to 14V and a wide output voltage of 0.5V to 4V. It also comes with advanced over-current protection that prevents potential damage when used under extreme loads.

Working Principle

The TPS5100IPWRG4 uses a combination of synchronous step-down DC-DC switching and voltage regulation to convert the input voltage to a regulated output voltage. This is accomplished by using a synchronous switching regulator that utilizes a control loop to monitor the output voltage and then adjust the internal switching frequency to maintain the desired output. This is also known as pulse width modulation (PWM) technique.

The controller uses the input voltage and an internal feedback signal to determine the duty cycle of the switching frequency. The duty cycle is then translated into a corresponding output voltage. The TPS5100IPWRG4 also features over current protection, thermal shut down and hysteresis, which prevent the device from being damaged due to abnormal operating conditions.

Power Saving Operation

The TPS5100IPWRG4 can be used in a number of power saving applications, including dynamic frequency control and voltage arm assisted adaptive current mode. Dynamic frequency control reduces the switching frequency when the load is low, reducing power consumption and extending the battery life of the system. The voltage arm assisted adaptive current mode dynamically adjusts the switching frequency based on system conditions, further reducing power consumption.

The TPS5100IPWRG4 also supports programmable switching frequency, allowing users to tailor the switching frequency as per their needs. This helps maximize the system efficiency and allows for custom solutions based on the application requirements. The TPS5100IPWRG4 can also operate in Burr Brown mode, allowing it to achieve up to 98 percent efficiency.
