For added flexibility, the TPS60120PWPRG4 also features an enable and a programmable soft-start functionality, as well as an integrated fast transient response for better EMI performance.

Applications of the TPS60120PWPRG4

The main applications of the TPS60120PWPRG4 are in the fields of industrial, mobile and automotive. Due to its wide input voltage range, the device is ideal for industrial applications that require a universal input voltage range from 2.4V to 5.5V. It is also suitable for mobile applications that need an output voltage of 3.3V to 40V and a programmable current limit. Furthermore, the TPS60120PWPRG4 is AEC-Q100 certified, which makes it suitable for automotive applications that require extreme temperature operation.

Working Principle of the TPS60120PWPRG4

The TPS60120PWPRG4 is a synchronous boost converter, which means that it uses a primary side MOSFET along with a secondary side synchronous FET that are driven in a 180° out of phase manner to reduce power loss and improve efficiency. The primary side MOSFET is switched by an external clock signal to alternately connect the input voltage source to either the high-side or the low-side of the inductor. The secondary side synchronous MOSFET is then switched on and off at the same frequency to then connect the inductor across the output voltage. This causes the inductor to store energy from the input voltage and then discharge it into the output voltage whenever the synchronous MOSFET turns on and off.As for the current limit protection, the device is equipped with a current sense input to monitor the output current. When the current reaches the programmed upper limit, the device will enter the current limit protection mode and shut down the secondary side FET. This prevents any further current from flowing out to the output and helps protects the device from over current.

Conclusion

The TPS60120PWPRG4 is a Synchronous Boost DC/DC switch regulator designed for automotive applications that require both low input voltage and high output voltage. Its features include a wide input voltage range of 2.4V to 5.5V, an output voltage range of 3.3V to 40V, an adjustable frequency of 800 kHz to1.5 MHz, a programmable current limit of 2.5 A to 7.5 A and an integrated fast transient response. This device is suitable for industrial, mobile and automotive applications and has been AEC-Q100 certified. It uses a synchronous boost converter topology to transfer energy from the input voltage source to the output voltage and utilizes a current sense input for current limit protection.
