TPS62730DRYR Step-Down Converter by Texas Instruments

The TPS62730DRYR is a high-efficiency, low-power step-down converter from Texas Instruments, designed to extend battery life in portable devices. This advanced power solution is ideal for energy-sensitive applications due to its exceptional power conservation capabilities and small form factor.

Operating at a voltage range of 2.2V to 5.5V, the TPS62730DRYR is versatile and can accommodate a wide array of battery technologies and configurations. It is particularly well-suited for single-cell, multi-cell alkaline, NiMH, NiCd, or single-cell Li-ion and Li-polymer batteries, making it a flexible option for designers.

The device boasts a high efficiency of up to 95%, achieved through its innovative DCS-Control™ topology. This feature allows for a seamless transition between step-down and power-save modes, ensuring optimal power management across varying load conditions. The TPS62730DRYR also includes a bypass mode, which provides a direct connection from the input to the output to further conserve power when the load is light.

With a low quiescent current of typically 360 nA during operation and 10 nA in shutdown mode, the TPS62730DRYR ensures minimal drain on the battery, thus prolonging device runtime. It also supports a maximum output current of 200 mA, which is sufficient for a multitude of low-power applications.

The TPS62730DRYR is available in a compact 2.00 mm x 2.00 mm VSON package, which is ideal for space-constrained applications. Additionally, it is designed with a fixed output voltage version and an adjustable version, providing designers with the flexibility to select the most suitable option for their specific requirements.

Key features such as over-temperature protection, output voltage supervision, and under-voltage lockout ensure the TPS62730DRYR operates reliably and safely under all conditions. This makes the TPS62730DRYR a robust and dependable choice for powering the next generation of portable electronics.
