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

TPS61240-Q1 device provides fixed output voltage of 5V-typ with an input voltage range of 2.3 V to 5.5 V and the device supports batteries with extended voltage range. During shutdown, the load is completely disconnected from the battery. The TPS61240-Q1 boost converter is based on a quasi-constant on-time valley current mode control scheme.

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

During light loads the device will automatically pulse skip allowing maximum efficiency at lowest quiescent currents. In the shutdown mode, the current consumption is reduced to less than 1 µA.

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