TPS51116RGETG4 is a special purpose voltage regulator mainly used in automotive applications. It is designed to provide a regulated supply voltage for the gate drive of a synchronous buck converter and has an integrated gate driver circuit to drive the power MOSFETs. This device can provide a variable output voltage range of 0.8V to 5.5V, making it suitable for a wide range of gate drive applications.

The TPS51116RGETG4 is an integrated solution that includes 4 regulation and 4 switching power stages. The peak load current capability of the device is 2.5A while the dual Gate Driver can provide up to 25A and 20A sink and source currents respectively. The device has a static on-resistance of 0.3 ohms, making it suitable for applications where power losses must be minimized.

The TPS51116RGETG4 is manufactured using an advanced Bipolar and CMOS integrated process. This allows for high efficiency, low temperature operation and fast response times. The operating temperature range of the device is -25°C to +85°C, making it suitable for applications in the automotive environment. The device has two device enable inputs that allow for the device to be disabled in case of fault or power-down conditions.

The working principle of the TPS51116RGETG4 is based on a hysteresis current mode control method. The device has an error amplifier that senses the input (Vin) and output (Vout) voltages. The output voltage is compared with a voltage reference and the error amplifier produces an output current which is proportional to the error. This output current is applied to the pulse width modulation circuit which produces a signal to the Gate drive which turns on or off the mosfets.

In summary, the TPS51116RGETG4 is an integrated voltage regulator designed for automotive applications. It is capable of providing a regulated output voltage of 0.8V to 5.5V and its integrated gate driver circuit provides up to 25A and 20A sink and source currents respectively. The device has a static on-resistance of 0.3 ohms, making it suitable for applications where power losses must be minimized. The operating temperature range of the device is -25°C to +85°C, making it suitable for automotive applications.
