TLV61224 Single-Cell, High-Efficient, Step-Up Converter in 6-Pin SC-70 Package 1 Features 3 Description 1 Up to 94% Efficiency at Typical Operating The TLV61224 device provides a power-supply Conditions solution for products powered by either a single-cell or 2-cell alkaline or NiMH, or 1-cell Li-primary battery. 5- A Quiescent Current Possible output currents depend on the input-to- Operating Input Voltage From V to 3 V output voltage ratio.

2 The boost converter is based on Pass-Through Function During Shutdown a hysteretic controller topology using synchronous rectification to obtain maximum efficiency at minimal Output Current of More Than 40 mA From a quiescent currents. The output voltage of this device Input is set internally to a fixed output voltage of 3 V. The Typical Switch Current Rating 400 mA converter can be switched off by a featured enable Output Overvoltage Protection pin. While being switched off, battery drain is minimized. The device is offered in a 6-pin SC-70. Overtemperature Protection package (DCK) measuring 2 mm 2 mm to enable Fixed 3-V Output Voltage small circuit layout size.
