3 Description
The TLV61224 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 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.
