Description for the TPS61240-Q1

The TPS61240-Q1 device is a high efficient synchronous step up DC-DC converter optimizedfor products powered by either a three-cell alkaline, NiCd or NiMH, or one-cell Li-Ion orLi-Polymer battery. The TPS61240-Q1 supports output currents up to 450 mA. The TPS61240-Q1 has aninput valley current limit of 500 mA.

TPS61240-Q1 device provides fixed output voltage of 5V-typ with an input voltage range of2.3 V to 5.5 V and the device supports batteries with extended voltage range. During shutdown, theload is completely disconnected from the battery. The TPS61240-Q1 boost converter is based on aquasi-constant on-time valley current mode control scheme.

The TPS61240-Q1 presents a high impedance at the VOUT pin whenshut down. This allows for use in applications that require the regulated output bus to be drivenby another supply while the TPS61240-Q1 is shut down.

During light loads the device will automatically pulse skip allowing maximum efficiencyat lowest quiescent currents. In the shutdown mode, the current consumption is reduced to less than1 µA.

TPS61240-Q1 allows the use of a small inductor and capacitors to achieve a small solutionsize. The TPS61240-Q1 is available in a 2 mm × 2 mm WSON package.

Carrier options

You can choose different carrier options based on the quantity of parts, including full reel, custom reel, cut tape, tube or tray.

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  tube or tray  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.
