TPS62203DBVT Description

Short technical summary and product information.

The Texas Instruments TPS62203DBVT is a high-efficiency synchronous step-down (buck) converter designed for power management applications. It operates with an input voltage range of 2.5V to 6V and delivers a fixed 3.3V output voltage at up to 300mA of current. This device boasts up to 95% efficiency, making it suitable for power-sensitive designs.

 

The converter features a 1MHz fixed-frequency PWM operation and a typical quiescent current of 15µA, contributing to its high efficiency across a wide load current range, especially due to its power save mode. It includes features like Enable, Light load efficiency, and Synchronous Rectification. The TPS62203DBVT is available in a compact 5-pin SOT-23-5 package, suitable for surface mount applications.

 

Its operating temperature range is -40°C to 85°C (TA), and it supports a 100% duty cycle for low-dropout operation. The fixed output voltage configuration simplifies design, while the synchronous rectification enhances efficiency. This component is ideal for applications requiring efficient voltage conversion in a small form factor.
