TLV61225DCKT Datasheet PDF - TI

●The TLV61225DCKT is a Step-up Converter 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 3.3V. The converter can be switched off by a featured enable pin. While being switched off, battery drain is minimized. It is controlled by a hysteretic current-mode controller. This controller regulates the output voltage by keeping the inductor ripple current constant in the range of 200mA and adjusting the offset of this inductor current depending on the output load.

● Up to 94% efficiency at typical operating conditions

● Pass-through function during shutdown

● Output overvoltage protection

● Overtemperature protection
