The typical quiescent current in PFM mode is 15 µA. - What are the available package options for the TPS62260DRVT?
The device is available in a 5-pin SOT and a 6-pin 2-mm × 2-mm WSON package. - What is the operating temperature range for the TPS62260DRVT?
The operating temperature range is from -40°C to 85°C. - Can the TPS62260DRVT be used in low noise applications?
Yes, the device can be forced into fixed frequency PWM mode by pulling the MODE pin high for low noise applications. - How does the voltage positioning feature work in the TPS62260DRVT?
The voltage positioning feature reduces voltage undershoots/overshoots at load steps by regulating the output voltage 1% higher than the nominal value in power save mode. - What is the thermal shutdown temperature for the TPS62260DRVT?
The thermal shutdown temperature is 140°C with a hysteresis of 20°C.
