• Handheld and Wearable Applications: TPS62005DGSR includes small form factor to reduce the devices\' footprint and makes them suitable for compact and slim devices.
• Automotive: TPS62005DGSR is used to reduce the oscillation of dimming devices and power LEDs.
• Small Sensor Electronics: With TPS62005DGSR, designers can implement small sensor electronics in various applications due to its always-on operating mode.
• Medical Electronics: TPS62005DGSR offers low EMI and high-end reliability for medical electronics.

Working Principles of TPS62005DGSR DC/DC Switching Regulators

As a non-synchronous DC/DC converter, the TPS62005DGSR uses the Charge Pump Methodology to generate the pulse width modulation. It works by switching between high-side and low-side transistors. When the high-side transistor is “on”, current will pass through and charge the inductor, and when the low-side transistor is “on”, current will discharge from the inductor and supply the output load. The switching between transistors regulates the output voltage and current.

By using this method, TPS62005DGSR can reach an efficiency level as high as 95%, which helps to increase the battery life and reduce the power dissipation of the system. The TPS62005DGSR also features integrated features such as current limit and soft start ramp time to make sure reliable operation when the load current is over 2.5A.

Conclusion

The TPS62005DGSR DC/DC switching regulator is suitable for applications that require high efficiency and current in a small package. Its application fields include portable electronics, handheld and wearable devices, automotive, small sensor electronics, and medical electronics. The main working principle of TPS62005DGSR is to switch between the high-side and low-side transistors that regulate the output voltage and current. It helps to increase the battery life, reduce power dissipation and ensure reliable operation in various applications.
