Description for the TPS62125
The TPS62125 device is a high-efficiency synchronous step-down converter optimized forlow and ultralow power applications providing up to 300-mA output current. The wide input voltagerange of 3 V to 17 V supports 4-cell alkaline and 1- to 4-cell Li-Ion batteries in seriesconfiguration as well as 9-V to 15-V powered applications. The device includes a precise low-powerenable comparator which can be used as an input supply voltage supervisor (SVS) to address systemspecific power-up and power-down requirements. The enable comparator consumes only 6-µA quiescentcurrent and features an accurate threshold of 1.2 V typical as well as an adjustable hysteresis.With this feature, the converter can generate a power supply rail by extracting energy from astorage capacitor fed from high impedance sources such as solar panels or current loops. With itsDCS-Control scheme the converter provides power-save mode operation to maintain highest efficiencyover the entire load current range. At light loads the converter operates in pulse frequencymodulation (PFM) mode and transitions seamlessly and automatically in pulse width modulation (PWM)mode at higher load currents. The DCS-Control™scheme is optimized for low-output ripple voltage in PFM mode in order to reduce output noise to aminimum and features excellent AC load regulation. An open-drain power good output indicates oncethe output voltage is in regulation.
NEW - You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.
A custom reel
is a continuous length of cut tape from one reel to maintain lot- and date-code traceability, built to the exact quantity requested. Following industry standards, a brass shim connects an 18-inch leader and trailer on both sides of the cut tape for direct feeding into automated assembly machines. TI includes a reeling fee for custom reel orders.
Cut tape is a length of tape cut from a reel. TI may fulfill orders using multiple strips of cut tapes or boxes to satisfy the quantity requested.TI often ships
devices inside a box or in the tube or tray, depending on inventory availability. We pack all tapes, tubes or sample boxes according to internal electrostatic discharge and moisture-sensitivity-level protection requirements.
