Introduction of TPS62150ARGTR

TPS62150ARGTR is a DC/DC buck converter with a 6 A integrated external N-channel BuckMOSFET, controlling an output current and supporting a synchronous reset feature. It is a Class-G switch mode power supply (SMPS) device that operates from an input voltage range of 2.5 V to 6.5 V and delivers an adjustable output voltage as low as 0.6 V. This switching regulator also supports a 3.2 MHz switching frequency and provides up to 97% peak efficiency. It is designed for various portable applications such as tablets, smart phones and video players.

Application Field

TPS62150ARGTR is an ideal device for battery-powered portable applications such as smart phones, tablets and video players. This device combines a 6 A buck-boost switch with adjustable output voltage from 0.6 V to 6 V and further supports an output current of up to 3 A. It operates over an input voltage range of 2.5 to 6.5 V and provides up to 97% peak efficiency.

TPS62150ARGTR can also be used to support high-current and high-voltage output voltage applications such as cameras, LCDs and other DC/DC sources. The device supports a Synchronous Reset feature that helps ensure efficient startup on low-voltage systems and stays off until an input voltage is applied. It also supports a 3.2 MHz switching frequency and a low quiescent current of 5 μA. In addition, the device is designed for small footprints and requires few external components for the design.

Working Principle

TPS62150ARGTR operates by regulating the output voltage of a DC/DC converter. The device uses a step-down switching regulator topology and a synchronous rectifier to deliver current to the load. When the output voltage reaches the set operating point, the device quickly switches the drain of the BuckMOSFET to ground and grounds the source at the same time. This action causes current to flow through the inductor and a capacitor connected in series, resulting in a high-side switch and low side switch, allowing the BuckMOSFET to reset itself and maintain regulated output.

The device also features an advanced Discharge feature, which allows the device to quickly reduce the output voltage across the inductor when the device’s operation is changed from On to Off. This feature also helps reduce power losses due to switch control. Furthermore, the device supports a 3.2MHz switching frequency and offers up to 97% peak efficiency which helps the system run cooler and extend battery life.

Conclusion

TPS62150ARGTR is a DC/DC buck converter with a 6 A integrated external N-channel BuckMOSFET, controlling an output current and supporting a synchronous reset feature. It is suitable for various portable applications such as tablets, smart phones and video players and helps reduce over-voltage, over-current and over-temperature conditions. TPS62150ARGTR supports a 3.2MHz switching frequency and a low quiescent current of 5 μA, delivering up to 97% peak efficiency. It is able to reduce power losses due to switch control and helps the system run cooler, extending battery life.
