The TLV61225 device provides a power-supply solution for products powered by either a
single-cell or 2-cell alkaline or NiMH, or 1-cell Li-primary battery. Possible output currents
depend on the input-to-output voltage ratio. The boost converter is based on a hysteretic
controller topology using synchronous rectification to obtain maximum efficiency at minimal
quiescent currents. The output voltage of this device is set internally to a fixed output voltage
of 3.3 V. The converter can be switched off by a featured enable pin. While being switched off,
battery drain is minimized. The device is offered in a 6-pin SC-70 package (DCK) measuring 2 mm × 2
mm to enable small circuit layout size.
