Description
The TPS62742DSSR is a high-efficiency, step-down DC-DC converter designed by Texas Instruments. It is optimized for low-power applications and features an ultra-low quiescent current, making it ideal for battery-powered devices. The converter operates at a 2.2 MHz fixed frequency, providing a good balance between efficiency and size, as it allows the use of small inductors and capacitors.
The TPS62742DSSR supports an input voltage range of 2.2V to 5.5V, making it suitable for single Li-ion cells or multi-cell alkaline configurations. It offers an output current of up to 300 mA, with an adjustable output voltage down to 1.2V in 100 mV steps.
Key features include its automatic transition between PWM mode for efficiency at higher loads and a low-power mode for improved performance at light loads. It also provides a load disconnect feature to prevent battery drain when the device is off. The TPS62742DSSR is housed in a compact package, making it an excellent choice for space-constrained applications.
