Texas Instruments  TPS61240TDRVRQ1

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.
